摘要
Traveling-wave parametric amplification of 0.5-GHz acoustic shear waves has been observed in CdS at room temperature. Acoustoelectric coupling provides the nonlinear interaction. Observed gain was about 10 dB/mm, which is comparable to that of the conventional acoustic amplifier. © 1968 The American Institute of Physics.
