An efficient and accurate technique for the incident-wave excitations in the FDTD method
(Institute of Electrical and Electronics Engineers, 1998-06)
An efficient technique to improve the accuracy of the finite-difference time-domain (FDTD) solutions employing incident-wave excitations is developed. In the separate-field formulation of the FDTD method, any incident wave ...
Fast direct (noniterative) solvers for integral-equation formulations of scattering problems
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 algorithm for scattering from planar arrays of conducting patches
(Institute of Electrical and Electronics Engineers, 1998-04)
A direct (noniterative) algorithm for the solution of the electromagnetic scattering from three-dimensional planar arrays of conducting patches is developed. For an N-unknown problem, the computational complexity of this ...
Efficient methods for electromagnetic characterization of 2-D geometries in stratified media
Numerically efficient method of moments (MoM) algorithms are developed for and applied to 2-D geometries in multilayer media. These are, namely, the spatial-domain MoM in conjunction with the closed-form Green's functions, ...
Fast noniterative steepest descent path algorithm for planar and quasi-planar patch geometries
The fast noniterative steepest descent path (SDP) algorithm for planar and quasi-planar patch geometries are discussed. The comparison of scattered fields as computed by the method of moments (MOM) and fast direct algorithm ...
