Geometrical acoustics at microwave frequencies
Abstract
This project has involved a broad investigation of the propagation characteristics of acoustic waves in inhomogeneous anisotropic media, with special emphasis on focusing and beam steering and an evaluation of potential device applications of the phenomena. Attention was directed particularly at the possibilities for realizing electronically-controlled focusing and scanning of acoustic beams, functions of interest in applications such as acoustic spectrometry and acoustic imaging.
