Paper Abstract

Incorporation of ferromagnetic materials into metamaterial systems provides an opportunity to tune microwave permeability with an external magnetic field, strongly affecting wave propagation. We characterize microwave properties of several soft magnetic materials with high permeability as possible candidates for such applications. In the range of the ferromagnetic resonance, the permeability of ferromagnetic/dielectric composites varies from positive to negative values. In addition, a low field absorption peak provides an additional possibility of tuning with low fields. Microwave propagation through metal-dielectric multilayered systems shows
