Abstract

A modified Time-domain Integral Equation (TDIE) method is proposed and used to calculate the transient electromagnetic scattering by arbitrary conducting objects.Some typical targets

including a pie-shaped plate

a cube

a sphere and a specific conical model

are analyzed and discussed using the Implicit Marching-On-in-Time scheme.The present approach gives correct transient responses from conducting objects

and late-time instability is not observed.
