Transverse Acoustic Waves In Finite Piezoelectric-Metal Superlattices

Abstract

In this communication, we study the propagation of transverse acoustic waves in a finite superlattice (SL) constituted of alternating piezoelectric and metal layers. Our objective is to determine: i) the transmission and reflection coefficients through a finite SL, ii) the confined modes related to the finite size of the SL and iii) the possibility of existence of the acoustic Brewster angle in these systems.
