Abstract

A numerical scheme, which hybridizes the element level dual field time domain finite element domain decomposition method (ELDFDD/TDFEM) and time domain boundary integral (TDBI) method to accurately and efficiently analyze open-region transient electromagnetic scattering problems, is proposed. The element level decomposition permits an efficient leapfrog-like explicit marching scheme to be used to integrate Maxwell equations in time. The hybridization with TDBI method ensures that an accurate solution can be obtained in the smallest computation domain possible. The accuracy and applicability of the proposed hybrid method is demonstrated by numerical experiments.
