Microwave Acoustical Loss Mechanisms in Crystals.

Abstract

The utilization of microwave devices at high frequencies depends on the availability of materials with low acoustic loss. In order to extend the present frequency range of these devices, new materials with lower losses are desirable. The study was undertaken in an effort to gain a better understanding of the mechanisms responsible for acoustic attention and thus to develop improved materials. Large high-quality crystals of YAG, gallium-doped YAG, Nb and Lu doped YAG, LiNbO3, and LiTaO3 were grown; and the attenuation of these materials was measured.
