Phononic meaning
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 … WebJul 15, 2004 · A flat slab of material focuses sound using ‘negative refraction’.
