Abstract

The complex permeability of nanowire arrays of different materials was measured at X-band using a cavity perturbation technique. Compared with ferromagnetic films of the same materials, a relatively high permeability with a low loss is obtained. Our results indicate that ferromagnetic nanowire arrays have important potential technological applications as magnetodielectrics for microwave devices such as variable attenuators, phase shifters, modulators, stop-band filters and power absorbing terminals
