Efficient (M)MIC-structure investigation based on fast spectral domain integral equation techniques

Abstract

The presented space/spectral domain integral equation concept with an improved spectral domain integration in cartesian wavenumbers shows a high computational performance applied to a wide range of different (M)MIC-structures. The outlined low performance of iterative linear equation solvers forms the main problem for the development of iterative MoM-concepts so far, but ongoing investigations of multilevel block-matrix strategies seem to offer very promising properties making them well-suited for future iterative MoM frameworks.
