A rotating system that includes an initially stressed piezo-electric substrate was the subject of analytical study SH waves. The and vacuum bonding are in good contact with corrugation, top border is treated as stress-free corrugation. About upper barrier both electrically open well short scenarios taken into consideration. Dispersion equations for circumstances a corrugated interface have been found. wave characteristics through framework suggested dependent on different geometrical physical factors investigated based numerical findings. looks at simultaneous simulated outcomes number were produced Mathematica 7 include rotation, inhomogeneity, phase velocity, initial stress, distribution structure under discussion. model examination has potential applications creation surface acoustic devices.
