Reciprocal conversion of shear body and surface acoustic waves on periodically perturbed solid state surface
Gulyayev Yu.V. , Kurach T.N. , Plesskii V.P.
We show that a pure shear body acoustic wave normally incident on a periodically uneven piezoelectric surface may be effectively converted into two pure shear surface electroacoustic waves, and a surface wave incident on a periodic structure may be effectively reconverted into a body shear wave.
