WebDec 27, 2024 · Phononic crystals (PCs) have recently been developed as effective components for vibration suppression and sound absorption. As a typical design of PCs, wave attenuation occurs in the so-called stop-band. However, the structural response is still significantly large in the pass-band. In this paper, we combine PCs and acoustic black … WebBritish Dictionary definitions for phonography phonography / ( fəʊˈnɒɡrəfɪ) / noun a writing system that represents sounds by individual symbolsCompare logography the … marco and lizzy

WebDec 1, 2005 · Phononic crystals make use of the fundamental properties of waves, such as scattering and interference, to create “band gaps” – ranges of wavelength or frequency within which waves cannot propagate through the structure. In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of … See more A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency.
