Characteristic Mode Method for Multi-Scale Quasi-Periodic Structures

Abstract

The conventional method of moment (MOM) is often difficult to achieve fast and accurate electromagnetic simulation for multi-scale quasi-periodic structures. In this paper, the electric field integral equation(A-EFIE) based characteristic mode(CM) is used as the entire-domain basis function to accelerate the electromagnetic simulation of multi-scale quasi-periodic structures. The numerical examples are given to show that the efficiency of AEFIE is greatly improved for multi-scale quasi-periodic structures.
