Calculation of the diffraction component of the frequency response of SAW devices
Abstract
A simplified analysis of diffraction distortions in SAW devices is presented for near-field conditions and a parabolic anisotropy of SAW velocity. Expressions for the diffraction component of the frequency response of various interdigital transducers are obtained which yield a simple relationship between the distortion level and the transducer parameters.
