TD-EFIE approach to transient analysis of arbitrarily-shaped conductors
The time domain electric field integral equation (TD-EFIE) approach to analysis of transient electromagnetic response of various kinds of antennas and scatterers is presented in this paper. The method is applicable to both closed and open bodies because of the usage of EFIE. In the analysis, impressed sources and the shape of the conductors are arbitrarily given. The conducting surface is modeled by planar triangular patches for numerical purposes. The effects of temporal basis function on the results are studies firstly, which shows that the choice of temporal functions is vital importance. To overcome the late-time oscillation and keep the accuracy of the solution, an averaging scheme has been proposed. A number of numerical examples are given and the results are compared with ones obtained from inverse discrete Fourier transform (IDFT). The good agreement between them shows the correctness and effectiveness of the method proposed.
