We propose development of accurate and efficient exact-physics computational electromagnetics (CEM) solvers for accurate evaluation of RF signature characteristics of complex targets of interest to MDA. For accuracy and modeling flexibility the proposed codes combine novel fast, high-order frequency- and time-domain algorithms put forth in recent yearswhich can accurately and efficiently resolve both low- and high-frequency behavior while accounting for scattering, transmission and absorption. These solvers have provided some of the most efficient PDE solution methods in existence: in some cases, our algorithms are up to one-thousand times faster, for a given accuracy, than some of the best alternative solvers. Our novel parallel CPU and GPU implementations of these algorithms, in turn, demonstrate a high degree of efficiency, and, in particular: perfect parallel efficiency for the time-domain algorithms, 50%-to-70% parallel efficiency for integral equation algorithms, and nearly optimal GPU speedups, by a factors as high as 90, from the corresponding CPU implementations (for single Tesla C1060 GPU). Existing partnerships with relevant industries will help secure a significant customer base for the forthcoming software products. In all, our company is favorably positioned to deliver a powerful software tool for analysis of RF missile signatures as described in Topic MDA11-039.
