Abstract :
The time-domain electric field integral equation (EFIE) is used along with marching-on in time for treating problems of transient scattering by arbitrary wires and surfaces. The conducting wire and surface are modeled by straight segments and planar triangular patches for numerical purposes. Comparisons of surface and wire current densities and backscattered far fields are made with the results from the inverse discrete Fourier transform (IDFT) of frequency-domain solution, and good agreement is obtained in each case.
