We investigate the tunable directional beaming of sound wave from a subwavelength slit
surrounded by asymmetric surface gratings. The surface gratings are optimally designed to …

In this work, the existence and propagation of acoustic Tamm states at the interface of air
and a face-centered cubic solid-fluid phononic crystal composed of spherical air voids …

Evanescent coupling between surface and linear-defect waveguide modes in a two-
dimensional phononic crystal of steel cylinders in air is numerically demonstrated. When the …

Existence and guiding properties of surface modes bound to the interface between a finite
two-dimensional phononic crystal and the host medium are experimentally and numerically …

It is numerically shown that surface modes of two-dimensional phononic crystals, which are
Bloch modes bound to the interface between the phononic crystal and the surrounding host …

In this paper, we systematically investigate a kind of highly localized nonleaky surface
acoustic waves (SAWs) in a simple system consisting of a monolayer array of disjunct steel …

This paper shows the design, fabrication, and characterization of the Bloch-mode
micromechanical resonators made by creating alternate defects to form a resonant cavity on …

Sharp bending of surface waves at the interface of a two-dimensional phononic crystal
(PnC) of steel cylinders in air and the method of using a diagonally offset cylindrical scatterer …

However evanescent coupling between acoustic waveguides has been well studied by the
mode-matching method in the literature, a proposed physical model based on the tunnelling …

A simple planar multilayer structure was proposed for the observation of acoustic Tamm
states. The theoretical and experimental studies show that acoustic Tamm states can be …
