Research to Provide a Theoretical Determination of Surface Acoustic Wave Velocity and Impedance Differences between Metal Strips and Free Surface Regions of Metallic Gratings.
Abstract
This interim report describes the scattering theory approach for calculating the shift in velocity and acoustic reflection caused by one electrode (which can be buried) in an infinite array. Piezoelectric loading as well as first and second order mechanical loading are considered. The results calculated from electrode geometry and material constants are presented in the form of scatter matrices from which transmission line model parameters are derived. The analysis is being extended to the finite array case and these results will be included in the final report. (Author)
