Abstract :
Gulyaev-Bleustein waves (GBWs) circulating on closed paths have been observed on CdS single crystal. Four round-trip transits were visible on the oscilloscope in the range of 20¿70 MHz, representing a total delay time of 190 ¿s. The resolution of the different output signals was achieved by means of selective amplification. The device had a narrow bandwidth (~1 MHz)at frequencies used.
