Parallel generalized method of moments for analysis of transient scattering from PEC objects

The state of art of transient simulation using integral equation (TDIE) based methods has grown by leaps and bounds over the past few decades, both in terms of late time stability and computational complexity. This paper aims to address two additional functionalities: (i) development of a framework to enlarge the spatial approximation space using the generalized method of moments (GMM), and (ii) development of a robust parallel framework for accelerating plane wave time domain (PWTD) augmented GMM solvers. Preliminary results using GMM based TDIE solvers demonstrate the first of the desired attributes. Further results on parallelization and its integration with GMM based TDIE solvers will be presented at the conference.
