Computational Electromagnetics
Abstract
Progress in the development of fast, error-controllable algorithms for the simulation of electromagnetic scattering throughout the frequency spectrum is reported. Advances are described in the development of (1) accelerated, high-order methods for the solution of general, penetrable scattering problems in the low-to-moderate frequency regime; (2) spectral methods for the solution of approximate high-frequency models (geometrical optics -GO-); and (3) general error-controllable high-frequency scattering solvers. Major accomplishments include the completion of work on (1) in relation with scalar scattering models and the extension of the algorithms to vector models and composite backgrounds; the design, implementation and refinement of a spectral/discontinuous Galerkin method to resolve the GO model in phase space; the advancement of a spectral inverse ray-tracing approach; the development of methods for the evaluation of high-frequency scattering off composite rough surfaces; the derivation of general high-frequency scattering solvers applicable to both single- and multiple-scattering configurations consisting of bounded obstacles in two and three dimensions; and the analysis and implementation of strategies to account for and accelerate the evaluation of multiple-scattering effects.
