Abstract :
A closed form expression is obtained for the electric field distribution that results when a voltage is impressed on a system of surface wave interdigital electrodes. The conventional assumptions of weak piezoelectric coupling and of electrodes long compared with acoustic wavelength are made. Equivalence with previously reported results derived by a spatial harmonics method is explicitly demonstrated.
