A recently developed compression and sparse solution strategy for electromagnetic problems is applied to integral-equation formulations of scattering from perfectly conducting targets in three dimensions. It is shown that the resulting representations of both the impedance matrix and its inverse are

## Abstract We consider the problem of solving the integral form of the radiative transfer equation in an atmosphere with optical thickness Ο~0~β«1. We propose two methods transforming this problem to a finite set of the independent problems of the same type set in an atmosphere with optical thickne
## Abstract A fast integral equation method, termed IEβFFT, is applied with the combined field integral equation (CFIE) for solving electromagnetic scattering problems of threeβdimensional (3D) electrically large targets. For closed conducting surfaces, the employment of CFIE eliminates the interna

## Abstract A marchingβonβinβtime (MOT)βbased scheme for the analysis of transient scattering from closed surfaces characterized by an impedance boundary condition (IBC) is described. The timeβdomain integral equations being solved involve no analytical approximation and are free of spurious soluti
