In this paper, a kind of sandwich phononic crystal (PC) plate with silicon rubber scatterers
embedded in polymethyl methacrylate (PMMA) matrix is proposed to demonstrate its low …

Localization of elastic waves, both in-plane and anti-plane waves, propagating obliquely or
perpendicular to periodic and randomly disordered layered composites with and without …

Dispersive characteristics of elastic waves propagating through laminated piezoelectric
phononic crystal with imperfect interfaces are studied in this paper. First, the transfer matrix …

Using finite element method, we have made a theoretically study of the band structure of
Lamb wave in a locally resonant phononic crystal strip waveguide with periodic soft rubber …

Nonlinear phononic crystals are receiving increasingly greater attention in the field of sound
absorption and vibration reduction. In this paper, we use the perturbation method to …

The concept of spatiotemporal damping is proposed to quantify the inherent wave
attenuation property of dissipative metamaterials. The concept of spatiotemporal damping is …

The reflection and transmission coefficients through multilayered structure of finite thickness
and the dispersive relations of Bloch waves in one-dimension infinite periodic structure …

Using a Green's function method, we present a comprehensive theoretical analysis of the
propagation of sagittal acoustic waves in superlattices (SLs) made of alternating elastic solid …
