Phononic crystals have been proposed about two decades ago and some important
characteristics such as acoustic band structure and negative refraction have stimulated …

Based on the Huygens-Fresnel principle, we design a planar lens to efficiently realize the
interconversion between the point-like sound source and Gaussian beam in ambient air …

Surface acoustic wave propagation on a microscopic two-dimensional phononic crystal
consisting of a square lattice of holes is imaged in two dimensions and in real time at …

We have investigated the focusing of the lowest-order antisymmetric Lamb mode (A 0)
behind a positive gradient-index (GRIN) acoustic metalens consisting of air holes drilled in a …

Through a systematic theoretical analysis, we find that coarse corrugations textured on rigid
surfaces are preferred to realize highly confined surface acoustic waves over a broad …

Routing and guiding acoustic waves around sharp corners without backscattering losses is
of great interest in the acoustics community. Sonic crystals are primarily utilized to design …

The one-dimensional monoatomic lattice chain connected by nonlinear springs is
investigated, and the asymptotic solution is obtained through the Lindstedt-Poincar´ e …

Phoxonic crystal is a promising material for manipulating sound and light simultaneously. In
this paper, we theoretically demonstrate the propagation of acoustic and optical waves …

We investigate the photonic and phononic surface and edge modes in finite-size three-
dimensional phoxonic crystals. By appropriately terminating the phoxonic crystals, the …

The paper studies the existence of surface acoustic waves in half-infinite one-dimensional
piezoelectric phononic crystals consisting of perfectly bonded layers, which are arranged so …
