Abstract
A number of filter structures utilizing acoustic surface waveguides and periodic arrays of reflecting strips to form multimoded resonant configurations are described. The devices described are analogous to the monolithic crystal filter in that an array of acoustically coupled resonators is obtained from a structure placed on a single substrate. The coupling between resonators is described in terms of trapped energy modes of the surface‐waveguiding structures.Keywords
