Abstract

Abstract The complex permeabilities of the permalloy nanorods and their composite in nonmagnetic matrix were calculated by the semi-empirical method. The mixture of nanorods with different aspect ratios exhibited the broadband frequency behaviors of the permeability. For the near-field conduction noise suppression applications, the electromagnetic wave absorption of the magnetic composite was evaluated by coplanar waveguide method. The permeability and the power loss effects of composite with the aspect ratios of nanorods were evaluated with the change of composite thickness.
