摘要：

A marching-on-in-degree (MOD)-based scheme has been developed to solve a Calderon 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 Calderon 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. (c) 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1069-1072, 2014
