Microwave Acoustic and Bulk Device Technique Studies.
Abstract
Work on a monolithic parametric convolver using guided surface acoustic waves in a piezoelectric zinc oxide film on a silicon substrate, and related topics, has been submitted for publication. Construction has been completed on the electronics package and microcomputer control system for an 8-bit A/D converter with 2 microsec converion time, using a SAW delay line as a linear signal processing element, and the system is ready for initial testing. High conversion efficiency has been observed in barium titanate capacitor laminates used as electrostrictive transducers. These elements, and also poled polyvinylidene fluoride films, are being investigated as nonlinear signal processing elements for use in focussed two-dimensional phased arrays. (Author)
