Accelerated Simulation of Low Frequency Applications using Protheus/MLFMA

In order to extend the applicability of integral equation based methods to the analysis of complex structures at lower frequencies, an efficient formulation of the low frequency fast inhomogeneous plane wave algorithm has been implemented in the Protheus/MLFMA simulation tool. The seamless integration of the new low frequency method with the well known multilevel fast multipole algorithm within Protheus/MLFMA delivers a method capable of efficient accelerated wideband analysis for a large range of applications such as integration of communication antennas on ships, design of wideband antennas and EMC tasks.
