Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

Phononic materials are periodically arranged building blocks in the form of material
properties, geometries, and/or boundary conditions. This synthetic architecture makes …

We combine experimental, numerical, and analytical tools to design highly nonlinear
mechanical metamaterials that exhibit a new phenomenon: gaps in amplitude for elastic …

We experimentally achieve wave-mode conversion and rainbow trapping in an elastic
waveguide loaded with an array of resonators. Rainbow trapping is a phenomenon that …

力学超材料是一类由人工微结构单元构筑的复合结构或复合材料, 具有天然材料所不具备的静
力学/动力学性能. 由于这些超常特性通常取决于微结构单元而非材料组分 …

In this paper we review recent progress on the analysis, experimental exploration, and
application of elastic wave propagation in weakly nonlinear media and metamaterials. We …

The propagation of waves in nonlinear acoustic metamaterial (NAM) is fundamentally
different from that in conventional linear ones. In this article we consider two one …

This paper focuses on the dispersion properties and mechanism of the one-dimensional
strongly nonlinear acoustic metamaterials (NAMMs) based on the homotopy method. The …

Mechanical metamaterials are man-made composite structures or materials constructed
from artificial microstructural units with extraordinary static/dynamic properties not found in …

We report the design procedure for an acoustic add-drop filter (ADF) composed of two line-
defect waveguides coupled through a ring resonator cavity (RRC) all based on a phononic …
