Homogenization and applications of ferromagnetic Nano-wires based metamaterials

A numerical homogenization method for extracting the equivalent electromagnetic parameters, in particular the dispersive and nonreciprocal permeability tensor, of ferromagnetic nanowire (FMNW) based metamaterials is presented herein this paper. With the effective material property obtained, the performance of FMNW microwave devices, such as integrated, double-band isolators and phase shifters, are analyzed using a full-wave simulation based on a domain decomposition method (DDM). Numerical examples validate the proposed homogenization method and illustrate the integration of the multi-physics solution strategy to characterize the effects of FMNWs employed in RF devices.
