In this paper we investigate spatial propagation effect behind the Photonic Crystal (PhC) with nontrivial dispersion properties, which leads to a near field focusing. We analyze and experimentally demonstrate full two-dimensional focus formation of light beams at visible frequencies behind the three-dimensional woodpile photonic crystal. Experimental results correspond well with numerical FDTD calculations as well as with the mode expansion studies. The focusing distance of 60-80 micrometers beh...
