High Performance Electromagnetic Simulation Tools.

Army Research Office Grant DAAH04-93-G-0453 has supported the purchase of 24 additional compute nodes that were installed in the Intel iPsC860 hypercube at the Univasity Of Kentucky UK, rendering a 32-node multiprocessor. This facility has allowed the investigators to explore and extend the boundiriesof electromagnetic simulation for important areas of Defense concerns including microwave monolithic integrated circuit MMIC designanalysis and electromagnetic materials research and development. The iPSC860 has also provided an ideal platform for MMIC circuit simulations. A number of parallel methods based on direct time-domain solutions of Maxwells equations have been developed on the iPSC860, including a parallel finite-difference time-domain FDTD algorithm, and a parallel planar generalized Yee-algorithm PGY. The iPSC860 has also provided an ideal platform on whichto develop a virtual laboratory to numerically analyze, scientifically study and develop new types of materials with beneficial electromagnetic properties. These materials simulations are capable of assembling hundreds of microscopic inclusions from which an electromagnetic full-wave solution will be obtained in toto. This powerful simulation tool has enabled research of the full-wave analysis of complex multicomponent MMIC devices and the electromagnetic properties of many types of materials to be performed numerically rathern than strictly in the laboratory.
