“…The subject of elastic wave propagation in various piezoelectric materials and structures has received increasing attention from the mechanics community in the last few decades. Recent results mainly include surface waves in piezoelectric half-space (Collet and Destrade, 2004;Collet and Destrade, 2005), elastic half-space covered by piezoelectric layer (Nie et al, 2020a;Zhang et al, 2022) or the reverse configuration (Liu and He, 2010;Huang et al, 2014), interface waves in piezoelectric bi-material (Yang and Yang, 2009;Otero et al, 2012), guided waves in piezoelectric plate (Zhang et al, 2012;Nie et al, 2020b), and multilayered plate (Gao and Zhang, 2020;Xia et al, 2021), functionally graded piezoelectric material (Liu et al, 2021;Lakshman, 2022) and so on. So far, most of the available results on elastic wave in piezoelectric materials and structures are for the infinite media extended in one or two dimensions.…”
