Analysis of Curved Waveguide Structures using the MPSTD Algorithm

摘要

In this paper,the multidomain pseudospectral time-domain (MPSTD) algorithm is applied to model the curved waveguide structures.In order to improve the stability of the MPSTD method,the design of a filtering procedure is discussed for corner singularities.By calculating the resonant frequencies and S-parameters of the waveguide structures,numerical results indicate that the MPSTD method can achieve high efficiency and accuracy when use to analyze curved objects.This paper presents a scheme to analyze the waveguide structures,and extends application field of the MPSTD method.
