The Solution of Time-Domain Combined Field Integral Equation for Transient Scattering by Conducting Surfaces of Arbitrary Shape
基于时域混合场积分方程求解目标瞬态散射特性

The time-domain EFIE and MFIE approaches produce late-time oscillation for transient scattering responses from conducting objects when the incident spectrum of the field contains frequency components,which may correspond to the internal resonance of the structure.A time-domain Combined Field Integral Equation (CFIE)is presented.This formulation is based on a linear combination of the time-domain EFIE with MFIE. Numerical results for the EFIE,MFIE,and CFIE are presented and compared with those obtained from the Inverse Discrete Fourier Transform(IDFT)of the frequency-domain CFIE solution.And the time-domain CFIE solutions devoid of any resonant components.
