In MR/FDTD the problem domain is broken into several independent FDTD subregion lattices. The subregions lattices are terminated with the use of a surface integrated radiation boundary condition applied simultaneously to all subregions providing mutual interaction between the subregions. The advantages of MR/FDTD for sparse modeling problems include computation and memory efficiencies that result from confirming the FDTD lattices to the space near objects and from the ability to use different lattices and/or lattice orientations within each subregion. MR/FDTD also eliminates the need for local absorbing boundary conditions. Comparison between MR/FDTD and classical FDTD is provided through numerical examples. © 1997 John Wiley & Sons, Inc.
