Abstract

ABSTRACTA marching‐on‐in‐degree (MOD)‐based scheme has been developed to solve a Calderón preconditioned time‐domain electric field integral equation (TDEFIE) for the analysis of transient scattering from an arbitrarily closed conducting object. By using the time‐domain Calderón identity, the TDEFIE is immune to dense mesh breakdown. With the use of weighted Laguerre polynomials as entire‐domain temporal basis functions and the Galerkin temporal testing procedure, the MOD algorithm overcomes the late‐time instability. Numerical results show that the proposed algorithm can give rise to rapidly convergent solutions. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1069–1072, 2014
