    In computational electromagnetic simulations, most validation methods have been developed to quantify the similarity of two datasets, making them an objective tool for test engineers to discuss data on a similar basis. However, these methods do not always agree with the expert's opinion. The main problem when a validation method is used, is not taking into account the 'preprocessing' required by the expert to analyse a particular characteristic in the comparison. In this study, two different preprocessing techniques are used to show the influence they have on the results of the validation methods in relation to the opinion of the expert.

    In this paper a method combining different types of simulation is used to evaluate transient interferences over a digital communication system at its frequency band. The method combines different simulation stages; the first one is an electromagnetic simulation, with FDTD numerical method, which is carried out to establish the level of the interference coupled to the digital communication system; at the second stage, the simulation of the transmitted data at the communication system is performed introducing the EM interference calculated at the first stage. The result of this co-simulation will be a BER and other useful indicators to quantify the degradation produced by the transient interference. To show the effectiveness of the co-simulation method first of all the method is validated comparing the results with other evaluation techniques, measuring a real interference over an RFID system. The RFID system is according to the ISO 14443 type B standard, and the interference generated is a burst according to 61000-4-4. Once the co-simulation method is validated, the co-simulation system is used to quantify and decide if an EMC redesign technique of the previous scenario is efficient enough to avoid degradation at the RFID system produced by the burst transient interference.

    Abstract —In this paper a new methodology for the prediction of the conducted-emission propagation in an in-house power- line network is presented. This methodology is based on the modal S -parameter characterization of the devices present in the power-line network, as well as on the modal modeling of branch- line connections. The modal S parameters relate common- and di ff erential-mode waves, and give more information regarding interference propagation. With this methodology, common- and di ff erential-mode attenuations, and modal conversion between common and di ff erential modes can be accurately predicted, which is of great interest for power-line communication devel- opment and conducted-emission mitigation. This methodology is tested by accurately predicting the interference levels up to 100 MHz of an in-house power-line network composed by thermal- magnetic circuit breakers, residual-current circuit breakers, single-phase wires and light bulbs.

    In recent years, computational electromagnetism has had a great development thanks to the computational systems speed increase and their cost reduction. With those improvements the mathematical algorithms are able to work properly with more practical EMC issues. The problem that arises many times is to become condent with the results, in other words, to be able to quantitatively validate the results of the numerical simulation. In this paper we present a method to evaluate the diference between results obtained by visual expert opinion and those obtained from the FSV method.

    In this paper, the electromagnetic emission measurements of an hybrid bus are presented. The measurements were carried out in different modes, i.e.: pulling away, running and braking. With the tests performed we analyze vehicle radiated emissions, passengers' safety and radiated transient interferences. To characterize this singular vehicle insitu measurements were carried out where non-controlled interferences sources (TV, radio broadcasting, ...) have to be taken into account.

    In recent years, there has been an increased requirement for validation of computer simulation and electromagnetic modelling. During the development and implementation of new simulation methods it is useful, if not essential, to verify the appropriate modelling and simulation by comparison with appropriate measures. However, few studies are using an objective validation method to quantify the quality of their results. This paper presents the comparison between measurements and simulations using the W-FSV validation method. Specifically, the study used the validation method for analyzing and quantifying the quality of the mesh in the method of finite differences in time domain when a transient disturbance appears.

    In the last years, numerical simulation has seen a great development thanks to costs reduction and speed increases of the computational systems. With these improvements, the mathematical algorithms are able to work properly with more realistic problems. Nowadays, the solution of a problem using numerical simulation is not just finding a result, but also to ensure the quality. However, can we say that the model results are correct regarding the behaviour of the system? In other words, how could we quantify the similarity between reality and simulations? To answer these questions, it is necessary to establish a validation criterion that allows an objective quantification of the difference between the results and the reality. Another way to say this is, how “true” our results are. In the case of numerical methods, the main objective is to replicate as closely as possible the behaviour of the "real" world through numbers. Normally, the results of the numerical methods are expressed in terms of graphics, pictures, etc. These results represent the view of reality that the chosen method provides. In order to affirm that the result of a numerical solution is fully consistent with the reality, it must be satisfied that: a. The mathematical model must incorporate all aspects of the real world. b. The numerical method has to solve exactly the equations of the mathematical modelling. The problem starts with these two conditions that guarantee the "truth" of the results, since none of them are fully accomplished and it must be admitted that the numerical prediction never completely matches the "real" world behaviour. Then you can only be sure that the numerical solution is a good approximation of the reality. Now, new questions arise: How much does the result obtained by a numerical method resemble the reality? How can we objectively quantify this similarity? The answers to these questions are those that give rise to the validation methods.

    A complete system able to measure complex impedance, both in magnitude and phase, of an automotive electrical load is designed. The development of such system emerged from the need of measure the impedance of these loads in a wide range of frequencies (100 kHz to 30 MHz) while being connected to power supply and in operation. This powered up condition introduces several problems when the impedance is measured by means of traditional instruments such as Vector Network Analyzers (VNA), which could be damaged by transients. Understanding the behaviour of electrical cars loads in the frequency domain is of primary importance not only for in-vehicle Power Line Communication (PLC) channels response, but also to understand electromagnetic emissions (EMI)problems related with this type of communications.

    In this paper a radiofrequency identification system according to standard ISO/IEC 14443 type-B is evaluated in presence of transient noise. This real time communication system working at 13.56 MHz is interfered in a controlled environment by different transient bursts varying their level, frequency and duration. The transient burst interference is applied in an AC main wire close to the system and the effect over the digital communication system is evaluated using two different methods. The first one is observing directly an RFID equipment in presence of transient signals, and the second one is capturing the interference in time domain an evaluating its effect by means of simulation. The RFID system is affected by these transient noises causing different types of errors. It is shown that it is essential to measure and evaluate in time domain the transient phenomena to ensure that the RFID system do not have susceptibility problems.

    This paper describes the modeling and analysis to modeling EMC immunity test by means of computer simulation with Finite Difference Time Domain (FDTD) method. To ensure the integrity of the results the log-periodic antenna was simulated separately and then included in a more complex model. Despite the many limitations of both the numerical models and the measurements, the models provide a satisfactory representation of the electrical field radiated by the antenna.

    This paper presents a review of the effect of electromagnetic interferences of mobile phones in medical environment. The review is focussed in two areas, EMI in implantable devices like pacemakers or ICD, and EMI in medical equipment in hospital areas with life supporting equipment like intensive care units (ICU) or operating rooms (OR). The applied methodology for interference testing is different for all the analyzed studies, and the results range from 100% of interfered devices to no effect. The majority of authors recommend maintaining a safety distance both between cellular phones and medical devices. Also, it is necessary to establish clear policies for the use of mobile phones in critical areas in hospitals. Finally, it is necessary to develop a family of EMC standards for testing insitu the effects of non-medical devices inside medical facilities. This will permit medical staff to take profit from new technologies in their daily work in a safe way.

    An increased requirement for validation of computational electromagnetic simulation and modelling through the publication of IEEE Standard 1597.1 brings to light some interesting issues surrounding the validation of transients. The structure of a transient event has three particular regions of interest that can have an influence on the results, of which only two are generally well defined. These are the initial quiescent phase from t = 0 to the transient event; the transient event itself up to the point where the energy has fallen to a predefined limit, and the post-transient phase where residual energy is still present in the system. This latter region is generally ill-defined and changes the way that a validation comparison should be made, from, for example a frequency domain coupling study where the region of interest is usually well defined. This study looks at the influence of the three regions on the validation results and suggests how the Feature Selective Validation (FSV) method can be applied in transient studies.

    The ITU’s (International Telecommunication Union’s) man-made noise levels are based on measurements performed in the 1970s. Some measurements have been carried out since then, showing that noise caused by automotive ignition systems has been reduced, but manmade noise in business areas and city centers increased, especially due to the widespread use of electronic systems. The interference scenario also changed, from analog communication systems in relatively free-space conditions, to digital systems in living areas, often semi-enclosed such as offi ces, industrial production plants, and even inside cars and trains. Several measurements have therefore been carried out to estimate the level of man-made noise in these semi-enclosed environments.

    The present article studies the influence of a car heatable windshield by means of an equivalent material that allows an appropriate meshing of the vehicle. This study has been performed analyzing the propagation of an electromagnetic radiated transient pulse generated by a wire inside a car with and without the windshield. The Finite Differences Time Domain (FDTD) is the method used to obtain the field coupled to antennas located inside and outside the car. We concluded that it is important to take into account the heatable windshield to make a suitable electromagnetic model of the vehicle.

    The purpose of this paper is to analyze the influence of the metallic structures of a realistic car body frame on the specific absorption rate (SAR) produced by a cell phone when a complete human body model is placed at different locations inside the vehicle, and to identify the relevant parameters responsible for these changes. The modeling and analysis of the whole system was conducted by means of computer simulations based on the full wave finite-difference time-domain (FDTD) numerical method. The excitation considered was an 835 MHz 2 dipole located as a handsfree communication device or as a hand-held portable system. We compared the SAR at different planes on the human model, placed inside the vehicle with respect to the free space situation. The presence of the car body frame significantly changes the SAR distributions, especially when the dipole is far from the body. Although the results are not conclusive on this point, this change in SAR distribution is not likely to produce an increase above the limits in current guidelines for partial body exposure, but may be signifi- cant for whole-body exposure. The most relevant change found was the change in the impedance of the dipole, affecting the radiated power. A complementary result from the electromagnetic computations performed is the change in the electromagnetic field distribution inside a vehicle when human bodies are present. The whole vehicle model has been optimized to provide accurate results for sources placed inside the vehicle, while keeping low requirements for computer storage and simulation time.
