The Experimental Registration of the Evanescent Acoustic Wave in YX LiNbO<sub>3 </sub>Plate

The Experimental Registration of the Evanescent Acoustic Wave in YX LiNbO<sub>3 </sub>Plate

Evanescent acoustic waves are characterized by purely imaginary or complex wavenumbers. Earlier, in 2019 by using a three dimensional (3D) finite element method (FEM) the possibility of the excitation and registration of such waves in the piezoelectric plates was theoretically shown. In this paper t...
