Surface wave propagation in one-dimensional layered substrate composed of hexagonal piezoelectric quasicrystals with an imperfect interface
To design and optimize piezoelectric quasicrystal (PQC) surface acoustic wave (SAW) devices, a detailed study of surface wave propagationspecifically Rayleigh and Love wavesin PQC-layered structures with weak interfaces is conducted. A hybrid LegendreLaguerre polynomial approach is developed to analytically solve the wave dynamic equations in these structures, overcoming the limitations of traditional Laguerre polynomial methods. The interplay between piezoelectric effects and weak interface characteristics is thoroughly analyzed. Notably, new phenomena are uncovered: weak interfaces in the phonon and phason fields reduce structural stiffness, whereas weak interfaces in the electric field increase it. These effects are especially prominent at frequencies exhibiting significant dispersion. Additionally, the weak interface is found to diminish the piezoelectric coupling of phonon modes in Love waves. The findings provide a strong theoretical basis for the design and optimization of PQC-based SAW devices.
