Engineering microwave properties of microwires
A correlation between the frequency of natural ferromagnetic resonance (NFMR) (1−12 GHz) determined from the dispersion of permeability and alloy composition (or magnetostriction between 1 and 40 ppm) of glass-coated microwires has been systematically confirmed. Absorption of composite (microwire pi...

| Summary: | A correlation between the frequency of natural ferromagnetic resonance (NFMR) (1−12 GHz) determined from the dispersion of permeability and alloy composition (or magnetostriction between 1 and 40 ppm) of glass-coated microwires has been systematically confirmed. Absorption of composite (microwire pieces embedded in a polymer matrix) screens has been experimentally investigated. Parallel theoretical studies suggest that a significant fraction of the absorption can be ascribed to a geometrical resonant effect, while a concentration effect is expected for the thinnest microwires. |
