Abstract : Analog network representations are given for crossed-field and in-line excitation of acoustic surface waves on piezoelectric crystals. Advantages of the analog formulation of the circuits are discussed and compared with earlier models. Enhanced physical insight, flexibility in adapting the circuits to describe modifications in device structure, and a rational approach to the approximation problem are the primary motivations for adopting models of this kind. Appendices describe electric field calculations, lumped element transmission line approximations, and piezoelectric forces produced by electrode arrays.
