Analysis of transient electromagnetic scattering from closed surfaces using a combined field integral equation
TLDR
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.Abstract:
In the past, both the time-domain electric and magnetic field integral equations have been applied to the analysis of transient scattering from closed structures. Unfortunately, the solutions to both these equations are often corrupted by the presence of spurious interior cavity modes. In this article, a time-domain combined field integral equation is derived and shown to offer solutions devoid of any resonant components. It is anticipated that stable marching-on-in-time schemes for solving this combined field integral equation supplemented by fast transient evaluation schemes such as the plane wave time-domain algorithm will enable the analysis of scattering from electrically large closed bodies capable of supporting resonant modes.read more
