Abstract

In this letter, the matching-on-in-order time-domain volume-surface integral equation method is used to analyze transient electromagnetic scattering from objects comprising both conductor and dielectric material. SWG and RWG basis functions are used as the spatial basis functions in dielectric region and on the conducting surface, respectively. Different orders of weighted Laguerre polynomials are used as temporal basis functions, and the relative expansion coefficients are solved recursively order by order. The spatial and temporal testing procedures are separate, and both of them are carried on with the Galerkin's method. Stable solutions are ensured, and several numerical results are given to verify the proposed method. © 2011 Wiley Periodicals, Inc.
