영문 초록

A time-domain combined field integral equation (TD-CFIE) is presented to obtain the transient scattering response from arbitrarily shaped three-dimensional (3-D) conducting bodies. This formulation is based on a linear combination of the time-domain electric field integral equation (EFIE) with the magnetic field integral equation (MFIE). The time derivatives in EFIE and MFIE are approximated using a central finite difference approximation and other terms are averaged over time. The time-domain CFIE approach produces results that are accurate and stable when solving for transient scattering responses from conducting objects. Numerical results with the backward and central finite difference are presented and compared with those obtained from the inverse discrete Fourier transform (IDFT) of the frequency-domain CFIE solution.
