ABSTRACT:
An ultrasound radiation device comprises a piezoelectric substrate, an interdigital arrangement of two comb-shaped electrodes formed on an upper end surface of the piezoelectric substrate, a counter electrode formed on a lower end surface of the piezoelectric substrate, an interdigital transducer formed on said upper end surface of said piezoelectric substrate, and an amplifier between one of the two comb-shaped electrodes and the interdigital transducer. If an electric signal is applied between the counter electrode and one of the two comb-shaped electrodes, a longitudinal wave composed of the main lobe and grating lobes is radiated into a material in contact with the counter electrode, as well as a Lamb wave is excited in the piezoelectric substrate. The Lamb wave is detected as a delayed electric signal at the interdigital transducer. The delayed electric signal is amplified by the amplifier, and used as an input electric signal again.
