Latest Patents

One of Yang's latest patents is titled "Surface acoustic wave devices using piezoelectric film on silicon carbide." This invention features an acoustic resonator that includes a piezoelectric thin film (PTF) on a carrier substrate. The PTF confines a fundamental shear-horizontal (SH0) surface-acoustic wave within itself. The design incorporates an input bus line connected to an input source and a ground bus line linked to a ground potential. Additionally, the resonator includes two grating reflectors positioned at either end of the PTF, along with interdigital transducers (IDTs) that facilitate the acoustic wave's propagation.

Another notable patent is focused on "Fifth-generation (5G)-focused piezoelectric resonators and filters." This invention involves a piezoelectric thin film that is suspended above a carrier substrate, designed to propagate an acoustic wave in a Lamb mode. The configuration includes signal and ground electrodes oriented in a transverse direction, separated by a gap where the acoustic wave resonates. The design also features release windows at both ends of the piezoelectric thin film, enhancing its functionality.
