Interaction of microwave electromagnetic waves with 3D magnetic metamaterials
Source abstract
Abstract
Abstract Metamaterials based on opal matrix and containing magnetic particles are studied both experimentally and theoretically and their complex refractive coefficients at frequencies of millimeter waveband are obtained by comparing the results of calculations with the experimental data on transmission and reflection coefficients and their variations with an applied magnetic field. The metamaterials under study contain metallic cobalt, nickel and iron particles, nickel–zinc ferrite and silver particles, or ferrite-garnet Nd 3 Fe 5 O 12 particles. A parameter, characterizing the nonuniformity of electromagnetic fields at different distances from a magnetic particle, has been introduced and calculated. It is found that the nonuniformity drastically varies depending on the distance from magnetic particle and on external magnetic field.
