Conformal finite difference time domain technique using efficient overlapping grid method to analyze curved structures

Abstract

In this paper, A Conformal finite-difference time domain (CFDTD) method using a conformal overlapping grid concept is explained. A circular micro-strip patch antenna is used as object to explain the CFDTD concept. The code is developed using MATLAB and corresponding results are explained and corresponding results compared with results produced from ADS Momentum tool. In this grid overlapping case Perfect Matched Layers are used at boundaries to truncate the unusable field components.
