Abstract :
An efficient algorithm is presented for fast computation of the mutual electromagnetic interactions between a large group of sources in low frequency applications. These calculations are performed iteratively using the method of moments (MoM) solution of electromagnetic scattering problems. The proposed algorithm is based on a plane wave expansion of the free space Green´s function and reduces the complexity of the field calculations from O(N2) to O(N).
