An equivalent-network approach is described for the analysis of surface-acoustic-wave gratings. Circuit parameters can be theoretically determined by applying the finite-element method to an infinite array. In this approach, all of the effects of piezoelectric perturbation, mechanical perturbation, and energy storage are taken into account. To show the validity and usefulness of this approach, examples are computed for groove and metallic gratings. Both short and open circuited metallic gratings are treated. For grooves on isotropic and Y-Z LiNbO3 substrates, the dependence of reflection characteristics on groove depth is investigated. For aluminum strips on X-112°Y LiTaO3 34°Y-X quartz, Y-Z LiNbO3, and 128°Y -X LiNbO3 substrates, the dependence on metallization ratio is investigated in detail
