Abstract

A method to efficiently apply Domain-Decomposition (DD) to the MoM via the Synthetic Function eXpansion (SFX) is presented. Special emphasis is placed on the automatic generation of block subdivision of an arbitrary structure, which is key for all DD approaches. The DD-SFX approach is integrated within an FFT-based fast solver. Numerical experiments are presented in order to validate the method.
