Abstract

Manifesting the piezoelectric and nonlocal effects on the propagation of surface waves in nanoscale smart structures can provide some new insights for the designs and applications of the nanoscale wave devices. Taking the nanoscale size effect into consideration based on the nonlocal theory, the propagation of Bleustein–Gulyaev (BG) wave in a nonlocal piezoelectric (PE) layer overlying a nonlocal piezoelectric (PE) half-space, is investigated. The dispersion relations and particular cases are derived for the open and short circuit conditions. The results show that wave propagation is highly affected by nanoscale size effects due to the nonlocality present in the media.
