TL;DR: In this article, the authors reported the realization of acoustic collimating beams by a two-dimensional phononic crystal, which has a negative effective refractive index of small magnitude, and measured the measured intensity field distribution in experiment further confirms this collimating property.

TL;DR: In this paper, the sensor application of a resonance-induced extraordinary transmission through a regular phononic crystal consisting of a metal plate with a periodic arrangement of holes in a square lattice at normal incidence of sound is presented.

TL;DR: In this paper, the authors studied the transmission response of acoustic waves through a water-immersed thin hard plate embedded with elastic inclusions and found that the resonant excitation of the localized bending mode in the included hard plate can explain the abnormal transmission effect.

TL;DR: In this article, the acoustic-induced interactions between a pair of identical elastic plates patterned with periodical structures have been observed in the subwavelength regime, and the dramatic effect stems from the resonant enhancement of the local field sandwiched between the double plates.

TL;DR: In this paper, the authors presented experimental demonstration of multi-particles trapping and patterning by the artificially engineered acoustic field of phononic crystal plate. And they showed that the enhanced acoustic radiation force, induced by the resonant transmission field highly localized near the sub-wavelength apertures, accounts for the particles self-organizing.
