摘要

瞬变电磁波与物体的相互作用可以用时域积分方程的方法来表示。对于导电物体或均匀可穿透物体，可以采用时域表面积分方程。传统的tdsi求解方法在空域采用矩量法(MoM)，在时域采用时间进行法(MOT)。本文提出了一种混合方案，在空间域采用Nyström方法，在时间域采用以Laguerre函数为基函数的MoM方法。最后以导电球的电磁散射为例，说明了该方法的优越性。

Nyström method solution for time-domain electric field integral equations

The interaction of transient electromagnetic (EM) wave with objects can be formulated by the integral equation approach in time domain. For conducting objects or homogeneous penetrable objects, the time-domain surface integral equations (TDSIEs) can be applied. Traditionally, the TDSIEs are solved by the method of moments (MoM) in spatial domain and a march-on in time (MOT) scheme in temporal domain. In this work, we propose a hybrid scheme in which the Nyström method is used in spatial domain while the MoM with Laguerre function as a basis function in the time domain is employed. The numerical example for EM scattering by a conducting sphere is presented to demonstrate the scheme and its merits can be observed.
