An elastic fiber based on phononic crystals
Scientific Reports, 2021 In this study, a novel elastic phononic crystal fiber has been presented for the first time. This proposed structure can expand the sonic communications field, significantly. In order to realize the elastic fiber performance, solid–solid phononic crystal

Hypersonic Phononic Crystals [PDF]
Physical Review Letters, 2005 In this Letter we propose the use of hypersonic phononic crystals to control the emission and propagation of high frequency phonons. We report the fabrication of high quality, single crystalline hypersonic crystals using interference lithography and show that direct measurement of their phononic band structure is possible with Brillouin light ...

Phononic Coupled-Resonator Waveguide Micro-Cavities
Applied Sciences, 2020 Phononic coupled-resonator waveguide cavities are formed by a finite chain of defects in a complete bandgap phononic crystal slab. The sample is machined in a fused silica plate by femtosecond printing to form an array of cross-shape holes.

Directional Bandgap Analysis in Phononic Crystal with Rectangular Super Cell Structure [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2022 Phononic crystals have promising applications in the field of elastic waves and to attenuate the vibrations with their extraordinary feature of stop bands also known as bandgaps. Due to periodicity in structure, the wave in certain band of frequencies is

Band gap engineering in simultaneous phononic and photonic crystal slabs [PDF]
, 2010 We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail

Phonon manipulation with phononic crystals [PDF]
, 2012 In this work, we demonstrated engineered modification of propagation of thermal phonons, i.e. at THz frequencies, using phononic crystals. This work combined theoretical work at Sandia National Laboratories, the University of New Mexico, the University of Colorado Boulder, and Carnegie Mellon University; the MESA fabrication facilities at Sandia; and ...
