Physics-Based High Performance Computing Using Higher-Order Methods for Broadband Applications in Computational Electromagnetics (CEM)

ABSTRACT numerical simulation of Maxwell's equations: 1) high frequency asymptotics, which treats scattering and Under sponsorship from various Department of diffraction as local phenomena, 2) solution of an integral Defense (DoD) organizations and a Cooperative Research equation (frequency domain) for radiating sources on (or and Development Agreement (CRADA) with the U.S. inside) the scattering body, which couples all parts of the Research, Development and Engineering Command, body through a multiple scattering process, and 3) the Army Research Laboratory (RDECOM-ARL), direct integration of the differential form of Maxwell's HyPerComp has significantly advanced the state of the art equations in time. Accurate prediction for broadband of time-domain, broad band electromagnetic simulations. electromagnetic illumination is currently too The TEMPUS (Time-Domain ElectroMagnetic Parallel computationally expensive to be effectively addressed by Unstructured Simulator) environment is a complete self multiple applications of even the fastest frequency contained code suite that includes computer aided design domain techniques. The integration of Maxwell's (CAD) geometry creation and repair, unstructured equations in time offers the most direct and general gridding for full-scale targets with general materials, solution for broadband radar scattering and propagation of scalable parallel code architecture, higher-order accurate electromagnetic pulses in real materials.
