Abstract

In this paper, an unconditionally stable implicit FETD algorithm combined with the FETI method is described. The method is general enough for arbitrary geometries, and yet capable of taking advantage of periodicity. Together with the first-order ABC, the method is applied to simulate the microstrip EBG structure. Through the periodicity of this structure, memory requirements are further reduced without sacrificing accuracy. The simulation results are well agreed with the results obtained by FDTD method.
