Fast direct solution algorithm for electromagnetic scattering from 3D planar and quasi-planar geometries
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 ...
Solution of radiation problems using the fast multipole method
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 ...
Comparison of surface-modeling techniques
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 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 ...
