RF Polymer

Leveraging Spectrum Magnetics’ expertise in large scale fabrication of nanomaterials together with University of Delaware’s know-how in the research of magnetodielectric materials with simultaneously large permittivity and permeability, we propose to design and fabricate RF polymers that promise applications in antenna with much improved functionalities in miniaturization, impendence matching, and bandwidth. Other various applications also exist such as microwave devices, filters, and DC/DC converters which have sizable market shares. Our preliminary analysis confirmed our design concept that magnetic materials with high permeability above 1 GHz must first be developed. Guide by the physics behind high frequency materials, we choose and modify materials to achieve high magnetization, high resistivity, and low demagnetization factor. These materials will be subsequently embedded in suitable polymers to achieve RF polymers with desirable properties. Our approach will provide a commercial manufacturing technology for making RF polymers. In Phase I, we will demonstrate as obtained RF polymers with permittivity and permeability larger than 5 above 1 GHz frequency.
