Numerical dispersion control in discrete wave simulations in electrically large structures using spectral elements

Research output: Contribution to journalArticle

Abstract

The purpose of this work is to examine the advantages offered by spectral methods in the improvement of the accuracy of differential-equation based wave simulations. Fundamentals of these methods and complete bibliography are presented. To determine the validity of these methods, complex geometries were taken as examples. Isoparametric mapping was also implemented. Results show that such mapping does not impact the exponential convergence of the spectral approximation.
