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

For classical waves such as light or sound, diffraction sets a natural limit on how finely the
details of an object can be recorded on its image. Recently, various optical superlenses …

Acoustic metamaterials can manipulate sound waves in surprising ways, which include
collimation, focusing, cloaking, sonic screening and extraordinary transmission …

The book provides a comprehensive presentation of the topic of phononic and sonic
crystals, including acoustic and elastic wave propagation in homogeneous and periodic …

We show experimentally and theoretically that super resolution can be achieved while
imaging with a flat lens consisting of a phononic crystal exhibiting negative refraction. This …

The paper presents an in-depth analysis of solid locally resonant acoustic metamaterials
(LRAMs) consisting of rubber-coated inclusions. Dispersion properties of two-dimensional …

In this letter, we numerically demonstrate focusing of the lowest antisymmetric Lamb wave in
a gradient-index phononic crystal (PC) silicon plate and its application as a beam-width …

The propagation properties of flexural wave in the periodic beam on elastic foundations are
studied theoretically. The wavenumbers and traveling wave characteristics in the beam on …

Metamaterials have demonstrated the possibility to produce super-resolved images by
restoring propagative and evanescent waves. However, for efficient information transfer, for …

We experimentally realized a planar acoustic superlens by a simple structure consisting of
periodically arrayed rigid slabs. Based on the excitation of guided modes and the moderate …
