Abstract
Electrically tunable millimeter wave resonators and methods for fabricating and operating the same are disclosed. Embodiments include tunable millimeter wave resonators utilizing rare-earth nickelates, such as samarium nickelate. Embodiments tune the resonating member to frequencies between 30 and 100 GHz by varying the electric field across a resonating member. Further embodiments include a resonating member mounted to (and optionally embedded in) a substrate with conductive material connected to the resonating member and the substrate, and the total thickness can be 0.2 millimeters or less, or 0.1 millimeters or less. Additional embodiments include resonating members with a maximum dimension of 0.3 millimeters. Some embodiments include a gap between the conductive material contacting the substrate and the conductive material contacting the resonating member. Additional embodiments include resonating members with a loss tangent of less than 0.001, a dielectric constant of at least 100, and/or a quality factor greater than 500.
