Abstract

Dispersion curves for 128 Lithium Niobate, YZ Lithium Niobate, 42 Lithium Tantalate, STX Quartz, STX+25 Quartz, ATX Quartz, and LGS crystals are calculated with modified Hasimoto´s program. Dependences of obtained COM parameters on the electrode width and thickness are approximated by polynomials and used for calculations of admittance of transducer and frequency response of surface acoustic wave device by P matrix technique. The modified soft allows to calculate any substrates, including ones with low electromechanical coupling coefficients, those are very difficult or even impossible for calculation by means of other known tools.
