Determination of the Optimal Physical and Mathematical Model and Weight Functions for Calculating the Topology of Counterpine Converters of Surface Acoustic Waves

Abstract

The article is devoted to the analysis of existing physical and mathematical models describing the operation of Rayleigh’s counter-pin converters of surface acoustic waves (SAW), which are widely used in acoustoelectronics in the creation of microelectronic devices of various functional purposes. The weighting functions are also analyzed, with the help of which the topology of the counter-in converters is adjusted in order to reduce the influence of Gibbs pulsations. The advantages and disadvantages of each of the physical and mathematical models, as well as weighting functions from the point of view of achieving the specified requirements for the characteristics of devices on the characteristic curve, are also considered.
