Abstract :
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.
