Abstract
The cornerstone of mimetic finite differentiation (FD) is that discrete gradients and divergences, in combination to a novel boundary flux operator satisfy an approximation to the Gauss Divergence thereom. In this paper, we propose a spatially staggered second-order discretization of the acoustic wave equation that fully exploits all these mimetic operators on the implementation of free surface and absorbing boundary conditions. Explicit time integration is carried out by using the standard thre...
