Acoustic Bandgaps of Phononic Penrose and Quasicrystals
arXiv:2007.03607
Abstract
Using 3D printing we manufactured two rodlike phononic crystals. Viewed from the top, one is a Penrose tile and the second is a quasicrystal. We explored the acoustic properties and band gaps for both in the frequency range of 5kHz to 25kHz.
