These strategies include the use of a hybrid domain-decomposition solver which combines the Finite-Difference Time-Domain (FDTD) method and the method of moments (MoM). The MoM domains are discretized by using a uniform Cartesian mesh to simplify the meshing problem, and this type of mesh provides the basis for defining the piecewise sinusoidal (PWS) basis functions. Likewise, the moment-matrix generation process is greatly simplified and enhanced in numerical efficiency by using the Equivalent Medium Approach (EMA) to circumvent the problem of generating the layered medium Green's function for the layered problem at hand, in addition to deploying the available GPU resources to reduce the matrix fill-in time even further. Moreover, the size of the generated MoM matrix can be reduced significantly by generating the reduced set of high-level basis functions on the selected domains, the underlying concept behind for instance the Characteristic Basis Function Method (CBFM).Show less >
