A robust parallel conformal finite-difference time-domain processing package using the MPI library

Abstract

We present a parallel conformal finite-difference time-domain (PCFDTD) technique using the MPI library, which carries out the field exchange between the neighboring processes in a highly efficient way. A robust conformal mesh-generation technique based on the proposed parallel-processing scheme is also described. In addition, this paper introduces some novel approaches to implementing the excitation sources, including rectangular and circular waveguides, lumped elements, matched terminators, and sub-gridding, as well as meshing and simulation-result collection in the parallel scheme. The efficiency of the parallel-processing FDTD code is analyzed through several typical examples. Several electrically large finite antenna arrays are presented to validate the proposed techniques.
