Abstract:

Theoretical and experimental investigations of electroacoustic interactions were conducted as a basis for development of active and passive acoustic devices. To demonstrate these phenomena, breadboard models of a 60 Mcsec electroacoustic amplifier with a 75 db maximum acoustic gain, a 200 micro-sec lossless delay line operating at 60 Mcsec, and a 1 Mcsec acoustoelectric oscillator, were constructed. Both bonded quartz and integral transducers were investigated. An integral delay line and an amplifier demonstrate the use of compensated-layer CdS transducers. Thermal effects are discussed including methods of heat sinking the crystals for use in continuous wave CW devices. Combination of Hall and negative-resistance elements were breadboarded for controlling frequency and impedance. Author
