Abstract
Dispersion relations for acoustic surface waves in piezoelectrics with periodic metal strips applied to the surface are developed. Particular emphasis is given to the modification in effective piezoelectric coupling due to strip geometry, and the details of the dispersion relations around the stop bands. The general results are applied to discuss devices such as multistrip directional couplers and strip-coupled amplifiers.
