GPU based FDTD solver with CPML boundaries

The use of graphical processing units has been recently documented for the implementation of the FDTD technique; however, little has been reported about the necessary additions to three dimensional GPU based FDTD codes to make the technique more useful for EM analysis and antenna design. This paper will detail the practical addition of a convolutional perfectly matched layer absorbing boundary to a three dimensional GPU accelerated FDTD code and present results of simulations with dielectric and conducting objects in the computational domain.
