The study of phononic materials and structures is an emerging discipline that lies at the
crossroads of vibration and acoustics engineering and condensed matter physics. Broadly …

We report a new class of tunable and switchable acoustic metamaterials comprising
resonating units dispersed into an elastic matrix. Each resonator consists of a metallic core …

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

We study wave dispersion in a one-dimensional nonlinear elastic metamaterial consisting of
a thin rod with periodically attached local resonators. Our model is based on an exact finite …

We propose a new type of concrete for the attenuation of elastic waves induced by dynamic
excitation. In this metamaterial, which we call metaconcrete, the stone, sand, and gravel …

Ways for controlling and adjusting the longitudinal wave band structures of one dimensional
(1-D) rod phononic crystals with magnetostrictive material are theoretically investigated by …

Periodic composite materials have many promising applications due to their unique ability to
control the propagation of waves. Here, we report the existence and frequency tunability of …

This paper presents results on the numerical and experimental studies of focusing and
waveguiding of the lowest anti-symmetric Lamb wave in micro-fabricated piezoelectric …

In this paper, we present the theoretical investigation of acoustic confinement and
waveguiding in two-dimensional phononic crystals with material defect states. In contrast to …

Confinement of light by subwavelength objects facilitates the realization of compact photonic
devices and the enhancement of light-matter interactions. The Fabry-Perot (FP) cavity …
