Love wave interaction in a thin film with a periodic surface corrugation

The Love wave interaction in an elastically isotropic thin film having a free surface with aw eak sinusoidal oorrugation, deposited on a semi-infinite substrateo f another elastically isotropicm aterial is investigated for the case of propagation normal to the length of the corrugation. With the help of a singular boundary perturbation procedure, asymptotically exact analytical expressions are deduced for the characteristics of the wave interaction. The theory is applied to obtain the characteristics of the selective reflection of a Love wave incident on a moderately long periodica rray of shallow grooves etchedo n the free surface. The characteristics of reflection of a Love wave are compared with the corresponding results for a Rayleigh wave.
