| 摘 要： | 应用时域电场积分方程方法分析了各类天线和散射体的瞬态电磁响应.在分析中,激励源的形式和导体的几何形状可以任意.首先探讨了不同时域基函数对计算结果的影响,同时为了消除后期振荡,而且保持计算结果的准确性,还提出了一种新的均衡方案.计算了一系列的实例,并将计算结果与采用离散傅立叶反变换法计算得到的结果进行了比较.它们之间良好的一致性说明了本文所提方法的正确性和有效性.

| Abstract: | 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 the analysis,impressed sources and the shape of the conductors are arbitrarily given.The effects of temporal basis function on the results are studies firstly.To overcome the late-time oscillation and keep the accuracy of the solution,a novel averaging scheme has been proposed.A number of numerical examples are given and the results are compared with ones obtained from inverse Fourier transform(IDFT).The good agreement between them shows the correctness and effectiveness of the method proposed. |
