Abstract
The analysis of quasiacoustic-wave excitation by the uniform interdigital transducer is approached from a field point of view. Fields within the transducer are expressed in terms of a set of normal-mode functions which have been defined specifically for the interdigital array. Dispersion relations for these normal-mode functions are found to display band-gap regions with complex wave numbers. The complex wave number is responsible for the excitation process and permits a solution of the boundary conditions at both ends of the transducer structure. It is shown that the radiation fields excited by the transducer grow according to the dictates of a sine hyperbolic function from one end of the transducer to the other.
