Broad-Band Effective Magnetic Response of Two-Component Metaferrite with Spherical Inclusions

The effective magnetic properties of two-component magnetic metamaterial are carried out in this study at the GHz frequencies. The metamaterial is a homogeneous isotropic dielectric material with periodically embedded spherical ferromagnetic inclusions. The inclusions are fully magnetized by a dc bias magnetic field. The expression of effective permeability tensor has derived in the study as well as the expressions of complex effective relative permeability in the direction of external magnetization and perpendicular to it.Analysis of the spectra of real and imaginary parts of the complex effective relative permeability is shortly made in the study.
