A robust parallel conformal FDTD algorithm and its application to electrically large antenna array simulation

In this paper, we describe an optimized parallel conformal FDTD technique in which the field exchange is carried out between the neighboring processors in a highly efficient way. A robust conformal mesh design technique, based on the proposed parallel scheme, is also developed. In addition, this paper introduces a novel approach to realizing the FDTD excitation and collecting the computed field values in the parallel processing scheme. Several representative examples are presented to validate the proposed techniques.
