Geometrical Acoustics at Microwave Frequencies
Abstract
The purpose of this investigation is to study focusing and deflection of microwave acoustic bulk wave and surface wave beams in inhomogeneous anisotropic solids and to evaluate potential device application of these effects. Initially, the emphasis was on strictly geometrical effects and on inhomogeneities induced by means of magnetic and electric fields applied to ferromagnetic and semiconducting crystals. The investigation was later expanded to include diffraction effects and optically induced inhomogeneities, using mechanisms such as photoconductivity in piezoelectric media.
