Abstract

A method for modeling singular electric currents near conducting edges within marching‐on‐in‐time (MOT) simulators is presented. The use of singular basis functions in MOT simulators presents unique challenges not encountered in frequency‐domain implementations. Numerical results demonstrate that the proposed expansion results in accelerated convergence for scatterers with sharp features. © 2002 Wiley Periodicals, Inc.

## 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 die
