Modeling of Dielectric Waveguide Structures with a Multilevel Dynamically Adaptive Mesh Refinement (AMR)-FDTD Method

Abstract

In this paper, the application of the adaptive mesh refinement finite-difference time-domain (AMR-FDTD) technique to the simulation of dielectric waveguide structures was discussed. Significant computational savings were demonstrated, in comparison with the conventional FDTD technique, while accuracy was largely preserved. This area of problems includes several large-scale applications of interest; modeling of such applications can be dramatically accelerated by employing the proposed technique
