Abstract
The attenuation of elasticsurface waves in crystalline quartz at frequencies of 316 MHz and 1047 MHz has been measured as a function of temperature between 4.2°K and 300°K. At temperatures below 30°K the absorption per cm was found to follow a T 4 law with an approximately linear frequency dependence. At the higher temperatures the absorption varied as ω2 and was independent of temperature. The surface waves were detected by direct piezoelectric transduction and by a new optical method.Keywords
