Unusual properties of two-component metamaterial medium with metal ferrite like inclusions in the microwave frequency range

Metamaterials are of practical interest because of unusual properties that are not available in the real nature: the enhancement of the dielectric and magnetic constants, their low (so called ULI materials) or negative values (so called L-H materials). In recent years scientists pay special attention to metamaterials with real part of the effective magnetic constant essentially different from 1. This is because the desired properties of conventional ferrites are seriously degraded at frequencies above 1 GHz. In this study, we shortly present the Effective Medium Theory (EMT) in the microwave frequencies for 2-D two component metamaterials as host dielectric materials embedded periodically with iron cylindrical and spherical inclusions saturated with a biasing magnetic field.
