Abstract

In this paper, a new absorbing-boundary condition derived from z-domain is presented and implemented for the transmission-line matrix method (TLM). When introduced for the 3D-TLM symmetrical condensed node simulations, it shows an excellent performance in suppressing instability caused by spurious modes. The numerical stability of the absorbing boundary operators has been studied.
