Systematic realization of double-zero-index phononic crystals with hard inclusions [PDF]
Scientific Reports, 2018 A systematic process is described to realize double-zero-index phononic crystals with Dirac-like points experimentally. This type of crystal normally has softer inclusion material than its surroundings medium, allowing mapping into a zero-index medium ...

Dispersion tuning and route reconfiguration of acoustic waves in valley topological phononic crystals [PDF]
Nature Communications, 2020 The valley degree of freedom gives additional flexibility to tunable phononic and photonic crystals. Here, the authors realise a honeycomb phononic structure where both the size of the cavities and of the air channel can be actively tuned, allowing ...

Journal of Low Frequency Noise, Vibration and Active Control, 2023 Vibration and noise pollution is one of the main pollution in modern society. In order to obtain good vibration damping effect, more effective phononic crystals should be designed. Based on the theory of elastic wave propagation in solids, three types of
