Efficient method of moments analysis of infinite and finite arrays of magnetic nanoclusters in the optical frequency range

Abstract

Multiple-scattering-based macro basis function approach complemented with the incomplete QR algorithm provides an efficient method of moments solution for the analysis of infinite and finite arrays of magnetic and magneto-electric nanoclusters. The efficiency and the accuracy of the combined approach have been validated with respect to the brute-force implementation of the method of moments and the finite element method-based commercial simulator Ansoft HFSS, respectively, for an infinite doubly periodic array of magnetic nanaoclusters in the optical frequency range.
