Abstract
Conference Title: 2013 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium) Conference Start Date: 2013, July 7 Conference End Date: 2013, July 13 Conference Location: Lake Buena Vista, FL, USA The computational complexity and memory requirements of multilevel plane wave time domain (PWTD)-accelerated marching-on-in-time (MOT)-based surface integral equation (SIE) solvers scale as O(NtNs(log2)Ns) and O(Ns1.5); here Nt and Ns denote numbers of temporal and spatial basis functions discretizing the current [Shanker et al., IEEE Trans. Antennas Propag., 51, 628-641, 2003]. In the past, serial versions of these solvers have been successfully applied to the analysis of scattering from perfect electrically conducting as well as homogeneous penetrable targets involving up to Ns [approximate] 0.5 × 106 and Nt [approximate] 103. To solve larger problems, parallel PWTD-enhanced MOT solvers are called for. Even though a simple parallelization strategy was demonstrated in the context of electromagnetic compatibility analysis [M. Lu et al., in Proc. IEEE Int. Symp. AP-S, 4, 4212-4215, 2004], by and large, progress in this area has been slow. The lack of progress can be attributed wholesale to difficulties associated with the construction of a scalable PWTD kernel. [PUBLICATION ABSTRACT]
