Transmission of acoustic waves through a Hertzian contact is demonstrated at 7 GHz. A zinc oxide transducer on a sapphire buffer rod is used to excite acoustic pulses which propagate into a sapphire flat through a direct Hertzian contact. Measurement of the reflected pulses yields a transmission loss through the contact of 1.2 dB.
