Effect of Microwire Alloy Composition, Orientation, and Content on the Microwave Properties of Glass-coated Alloy Microwire Composites
The microwave properties of microwire alloy composition, the orientation of microwires, and the content of glass-coated FeCuNbVSiB, FeSiBCMn, and CoFeNiSiB microwire composites were studied. The transmission/reflection (T/R) coaxial line method was used to measure the relative complex permeability and complex permittivity for the microwire/rubber composites. The measured results show that the microwave permeability of randomly oriented glass-coated microwires is the highest, while that of the radially oriented glass-coated microwires is the lowest for different microwires orientation. The resonance frequency of the FeSiBCMn microwires and the permeability of the CoFeNiSiB microwires are the highest for different microwire alloy composition. The microwave permittivity of radially oriented glass-coated microwires is the strongest, the axially oriented glass-coated microwires is the lowest for different microwires orientation. The permittivity of the FeCuNbVSiB microwires is the highest for different microwire alloy composition.
