Abstract

The known electrical boundary-value problem for interdigital transducers is solved by methods of electrostatics in the general case of arbitrary number of different elastic electrodes per periodic cell. The electric admittance matrix elements, relating electrode currents with voltages, are obtained. These elements are represented as ratios of dispersion equation left-hand sides corresponding to various electrode connections. The frequency dependence of electrical admittances for some multi-electrode periodic cells is calculated.
