Abstract 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.
