Abstract
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 Nystrom 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.
