An Optimized Six-Step LOD-FDTD Method using the Artificial Anisotropy Parameters

Abstract

Using the artificial anisotropy (AA) parameters, an optimized six-step locally one-dimensional (LOD6) finite-difference time-domain (FDTD) method is developed. The proposed AA-LOD6 method and the existing LOD6 method take same simulation time, but it exhibits significantly low numerical dispersion error than the existing LOD6 method. Further, the performance of the AA-LOD6 method is compared here with the existing LOD6 method for the different mesh-sizes, time-steps, and operating frequencies. © 2022 European Microwave Association (EuMA).
