Abstract

This article presents improved adaptive domain decomposition finite difference time domain(IADDFDTD).We apply adaptive boundary test to the voltage on the boundary. The new algorithm avoids computational error caused by instability of electric field intensity on test boundaries, and can get more sub-domains
than the original ADD-FDTD and enhance computation speed. Analysis on applications of waveguide discontinuities indicates correctness and effectiveness.

Key words： adaptive domain decomposition; FDTD; boundary testing; waveguide discontinuities
