FDTD Algorithm for Numerical Anatomical Models With Cells Containing Several Debye Media

Abstract

In this article, we show that the previously published finite-difference time-domain (FDTD) thin-layer technique in De-bye media can also be used to account for FDTD cells filled with several media. This permits either the accuracy to be improved or the computational time to be reduced by increasing the cell size. The numerical experiments were performed with a 2-D slice of an anatomical model.
