Comparative evaluation of absorbing boundary conditions using Green's functions for layered media
(IEEE, 1995)Absorbing boundary conditions are comparatively studied using the Green's functions of the vector and scalar potentials for multilayer geometries and general sources. The absorbing boundaries are introduced as additional ... -
Comparative study of acceleration techniques for integrals and series in electromagnetic problems
(IEEE, 1995-06)Most of the electromagnetic problems can be reduced down to either integrating oscillatory integrals or summing up complex series. However, limits of the integrals and the series usually extend to infinity. In addition, ... -
Comparison of surface-modeling techniques
(IEEE, 1997-07)Solution techniques based on surface integral equations are widely used in computational electromagnetics. The accurate surface models increase the accuracy solutions by using exact and flat-triangulation models for a ... -
Fast direct (noniterative) solvers for integral-equation formulations of scattering problems
(IEEE, 1998)A family of direct (noniterative) solvers with reduced computational complexity is proposed for solving problems involving resonant or near-resonant structures. Based on the recursive interaction matrix algorithm, the ... -
Fast direct solution algorithm for electromagnetic scattering from 3D planar and quasi-planar geometries
(IEEE, 1997)A non-iterative method and its application to planar geometries in homogeneous media is presented. The method is extendable to the cases of quasi-planar structures and/or layered-media problems. The fast direct algorithm ... -
Fast multipole method in layered media: 2-D electromagnetic scattering problems
(IEEE, 1996)In this study, the Fast Multipole Method (FMM) is extended to layered-media problems. As an example, the solution of the scalar Helmholtz equation for the electromagnetic scattering from a two-dimensional planar array of ... -
On the choice of basis functions to model surface electric current densities in computational electromagnetics
(Wiley-Blackwell Publishing, Inc., 1999-11)Basis functions that are used to model surface electric current densities in the electric field integral equations of computational electromagnetics are analyzed with respect to how well they model the charge distribution, ... -
Solution of radiation problems using the fast multipole method
(IEEE, 1997-07)Electromagnetic radiation problems involving electrically large radiators and reflectors are solved using the fast multipole method (FMM). The FMM enables the solution of large problems with existing computational resources ...
