ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,512,813, issued on Dec. 30, was assigned to Qorvo US Inc. (Greensboro, N.C.).
"Lateral field excitation acoustic resonator" was invented by Marc Solal (Longwood, Fla.) and Robert Aigner (Ocoee, Fla.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Lateral field excitation acoustic resonators and methods of manufacture are disclosed. In one aspect, an acoustically resonating material such as a piezoelectric film or membrane is spaced from a substrate by electrodes having an air gap therebetween. When current flows through the electrodes, lateral field acoustic waves are excited in the resonating material with relatively good coupling and adequate heat diss...
