Integral equation formulations are a competitive strategy in computational electromagnetics
but, lamentably, are often plagued by ill-conditioning and by related numerical instabilities …

In this paper, a new technique for preconditioning electric field integral equations (EFIEs) by
leveraging CalderÓn identities is presented. In contrast to all previous CalderÓn …

The aim of this paper is to provide an introduction to the improved iterative Krylov solution of
boundary integral equations for time-harmonic scattering problems arising in acoustics …

This paper addresses the derivation of new second-kind Fredholm combined field integral
equations for the Krylov iterative solution of tridimensional acoustic scattering problems by a …

Novel time domain integral equations for analyzing scattering from perfect electrically
conducting objects are presented. They are free from DC and resonant instabilities plaguing …

Time domain electric field integral equations often are used to analyze transient scattering
from perfect electrically conducting objects. When discretized using marching-on-in-time …

We present a new class of integral equations for the solution of problems of scattering of
electromagnetic fields by perfectly conducting bodies. Like the classical Combined Field …

A Calderon multiplicative preconditioner (CMP) for the combined field integral equation
(CFIE) is developed. Just like with previously proposed Calderon-preconditioned CFIEs, a …

We present a systematic analysis of the integral operators of potential theory that arise when
solving the Helmholtz or Maxwell equations in the exterior (or interior) of a sphere in the …

We present several versions of Regularized Combined Field Integral Equation (CFIER)
formulations for the solution of three dimensional frequency domain electromagnetic …
