A spectral theory of single-phase unidirectional transducers of the surface acoustic waves is presented. It helps to evaluate the stop-band width where the directionality takes place, and allows one to optimize the transducer structure in order to obtain its symmetric frequency response, with maximum directionality at the stop-band center.

The aim of this publication is to design a procedure for the synthesis of an IDT (interdigital transducer) with diluted electrodes. The paper deals with the surface acoustic waves (SAW) and the theory of synthesis of the asymmetrical delay line with the interdigital transducer with diluted electrodes. The authors developed a theory, design, and implementation of the proposed design. They also measured signals. The authors analysed acoustoelectronic components with SAW: PLF 13, PLR 40, delay line with PAV 44 PLO. The presented applications have a potential practical use.

In the paper, which deals with the surface acoustic waves, is given the theory of synthesis of the asymmetrical delay line with the interdigital transducer with diluted electrodes. Based on derived theory, an experimentally verified delay line for use in the identification system, filters and resonators based on SAW for further specific applications has been designed.

Plane-wave theory of interdigital transducers comprising multi-strip periodic cells working in Bragg regime

Interdigital transducers of surface acoustic waves are periodic or nearly periodic systems of strips. In several applications they work in the Bragg regime to obtain strong surface wave Bragg reflections. This paper presents generalization of the spectral, full-wave theory to the case of transducers exploiting periodic cells comprising many strips of arbitrary width and positions within the cell. A novel method is applied to solve the dynamic boundary-value problem by means of the generalized electrostatic analysis. The generalization is useful for two purposes: for analysis of transducers having substantially aperiodic strips (by applying large cell periods with respect to the transducer length), and for analysis, in the frame of spectral theory, of unidirectional transducers exploiting cells comprising several different strips and certain interconnections between them within each cell. The theory yields full characterization of such transducers, including the surface wave dispersion characterized by stopband frequencies, and the transducer directionality.
