TLDR
In this article, the authors used the time-domain electric field integral equation (EFIE) along with the method of moments to develop a simple and efficient numerical procedure for treating problems of transient scattering by arbitrary shaped conducting objects.Abstract:
The time-domain electric field integral equation (EFIE) is used along with the method of moments to develop a simple and efficient numerical procedure for treating problems of transient scattering by arbitrary shaped conducting objects. The conducting surface is modeled by planar triangular patches for numerical purposes. Because the EFIE is used in the solution procedure, the method is applicable to both open and closed bodies. the EFIE approach is applied to the scattering problems of Gaussian plane wave illumination of a flat square plate and sphere. Comparisons of surface current densities and far-scattered fields are made with previous computations and good agreement is obtained in each case. >read more

Nonorthogonal PEEC formulation for time- and frequency-domain EM and circuit modeling
TL;DR: The PEEC formulation is systematically extended to nonorthogonal geometries since many practical EM problems require a more general formulation and is consistent with the classical PEEC model for rectangular geometry.

A space-time discretization criterion for a stable time-marching solution of the electric field integral equation
TL;DR: In this paper, a particular formulation of the method of moments which relies on a triangular-patch geometrical model of the exterior surface of the scattering body and operates according to a "marching-on-in-time" scheme is presented.

The plane-wave time-domain algorithm for the fast analysis of transient wave phenomena
TL;DR: It is shown that the computational cost of performing a surface-scattering analysis, using two-level and multilevel PWTD-enhanced MOT schemes, scales much more favorably than that of classical MOT schemes.

Analysis of transient electromagnetic scattering from closed surfaces using a combined field integral equation
TL;DR: In this article, a time-domain combined field integral equation is derived and shown to offer solutions devoid of any resonant components, which can be used for the analysis of transient scattering from closed structures.

Transient scattering from conducting cylinders
C. Bennett,W. Weeks +1 more
TL;DR: In this paper, a method for determining the fields scattered by arbitrarily shaped cylindrical conducting structures with a transient incident wave is described, where the transient scattering problem is reduced to the solution of a time domain integral equation which in turn is solved directly in the time domain by means of a digital computer.

Instabilities in time marching methods for scattering problems
TL;DR: The occurrence of exponentially increasing instabilities is a common feature of time marching methods for solving transient scattering problems as discussed by the authors, and the mechanism by which such instabilities arise and various methods of reducing their effect are described.
