Abstract
High performance bulk-wave transducers employing alternating half-wavelength thick piezoelectric and acoustically matched metal films have been fabricated to operate in Ku-band. Longitudinal-mode transducers employing zinc oxide and copper films fabricated on sapphire substrates yielded an untuned conversion loss of 25 dB from 8 to above 14 GHz.
