Calculation of thermostable directions and the influence of bias electric field on the propagation of the Lamb and SH waves in langasite single crystal plates


الملخص بالإنكليزية

Paper is presented the results of computer simulation. Effect of the dc electric field influence on the propagation of Lamb and SH waves and its temperature coefficients of delay in piezoelectric langasite crystal plate for a lot of cuts and directions have been calculated. There were found the cuts possessing the thermostability and sufficient electromechanical coupling.
