...Hao Gao; Yegao Qu; Guang Meng Phononic crystals are periodically engineered structures with special acoustic properties that natural materials cannot have. One typical feature of phononic crystals is the emergence of band gaps wherein the wave propagation is prohibited due to the spatial...

... April 25, 2013. Assoc. Editor: Liang-Wu Cai. 28 05 2011 29 01 2013 In this paper, acoustic wave propagation in a two- or three-dimensional phononic crystal consisting of Helmholtz resonators embedded in a fluid matrix is studied. The band structures are calculated to discuss...

.... More recently, Bloch analysis has found application in periodic macroscale materials, such as photonic and phononic crystals. In the vibration analysis of phononic crystals, structural damping is present together with energy dissipation. As a result, application of Bloch analysis is not straightforward...

...Zi-Gui Huang; Zheng-Yu Chen Previous studies on photonic crystals raise the exciting topic of phononic crystals. This paper presents the results of tunable band gaps in the acoustic waves of two-dimensional phononic crystals with reticular geometric structures using the 2D and 3D finite element...

... applications ( 4 5 6 ). The photonic band gap, a range of frequency in which electromagnetic waves cannot propagate, is of interest to engineers in designing photonic devices ( 7 ). Because of the similarity between stress wave propagation in phononic crystals and electromagnetic waves in photonic crystals...
