Abslrucl-Mm loaded rMp, slot, and Av/v surface acoustic waveguides on anisotropic substrates are ?heoretidy analyzed using a single scalar potential and wave equation. The scalar theory has the advantages of mathematical simplicity and can be applied with generality to the practical case of very thin films. A variety of surface waveguide problems can be described and analyzd in termcl of several 5xed parameters which are well known or easily measured. Waveguide dispersion curves and coupling coefficients for parallel waveguides are given. Experimental results for waveguides on LiNbO, and Bil,GeOl are prenented which substantiate the theory’s Validity.
