Frequency ranges of various magnetic materials and resonator designs.

Under the umbrella of communications, our research is focused on developing ultra-broadband tunable resonators, filters, and other wireless components to enable a single device to communicate across a wide range of frequencies and into the terahertz regime. It will focus on the design of high frequency resonators using antiferromagnetic/piezoelectric material composites with millimeter-wave and THz-range magnetic permeabilities and voltage-controlled tunability via strain-induced changes to the permeability. By incorporating antiferromagnets into such devices, this research will open the door to a new genre of THz tunable devices.
