| Abstract: | A modified Time-domain Integral Equation (TDIE) method is proposed and used to calculate the transient electromagnetic scattering by arbitrary conducting objec ts.Some typical targets,including a pie-shaped plate,a cube,a sphere and a spec ific conical model,are analyzed and discussed using the Implicit Marching-On-i n-Time scheme.The present approach gives correct transient responses from condu cting objects,and late-time instability is not observed. |
