This Phase I SBIR proposal aims to develop flexible and maritime compatible radio frequency (RF) materials for microwave absorbing material applications and antenna applications at GHz frequencies. Based on the deep understanding of material physics for high frequency properties, and extensive experience in fabricating and supplying RF materials, Spectrum Magnetics proposes several material platforms featuring high magnetic permeability and permittivity. The innovative approach to fabricate flexible ceramic materials allows high concentration of magnetic constituent in composites, therefore retaining high magnetic permeability. The magnetic permeability and permittivity of the composites can be tailored to offer greater design flexibility in microwave devices. The composite materials are maritime compatible. The materials are designed such that industrial standard manufacturing practices can be used to shorten the time for commercialization.
Benefit: It is anticipated that microwave absorbing materials with an index of refraction above 10 can be quickly developed. It is also feasible to develop antenna materials with index of refraction of above 10. These materials offer broad applications in miniaturized antenna and electromagnetic interference which are widely used in all DoD branches, civilian markets in telecommunication, autonomous vehicles, drones, smart gargets, and health care.
