ECE Associate Professor Cristian Cassella was awarded a patent for “High quality factor integrated acoustic resonant metamaterials with large frequency tuning range for reconfigurable radio-frequency front-ends.”
Abstract Source: USPTO
Piezoelectric acoustic metamaterial resonators include a piezoelectric substrate having a top surface and a bottom surface and a plurality of magnetostrictive members disposed on the top surface of the piezoelectric substrate and extending along a length of the piezoelectric substrate and spaced across a width of the piezoelectric substrate.
