Analysis Technique for Radiation Problems with Multiple Sources Combining Ray-Tracing and Macro-Basis Functions

摘要

This document presents a numerical approach for the solution of large electromagnetic problems using a preliminary ray-tracing analysis in order to determine the number of high-level macro-basis functions to be assigned to each block. It is especially tailored to problems with multiple sources or excitations. We provide expressions to update the threshold levels for the truncation of the number of Macro Basis Functions based exclusively on the position of the sources or including their radiation pattern.
