A Universal Framework for Non-Deteriorating Time-Domain Numerical Algorithms in Maxwell's Electrodynamics

Abstract

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens principle and lacunae of Maxwells equations.
