WebDec 22, 2006 · This is more than 5% faster than the velocity of a Rayleigh wave propagating at the surface of a phononic crystal in which ρA,B and C ijmn A, B are constant along the cylinder axis (i.e., h is infinite), namely 2488 m s −1. This might be related to the effect of the silicon substrate. Download : Download full-size image. WebApr 29, 2024 · This work proposes a method to design phononic crystal reflectors efficiently. For a prove of concept, a kind of quasi-surface acoustic wave and bulk acoustic wave (SAW/BAW) hybrid-coupled resonator with phononic crystal as reflectors is studied. The proposed design is implemented on the aluminum nitride (AlN) thin film with a high …

WebWe present a phononic crystal to achieve efficient manipulation of surface acoustic waves (SAW). The structure is made of finite phononic micro-ridges arranged periodically in a substrate surface. Each ridge is constructed by staking silicon and tungsten layers so that it behaves as one-dimensional phononic crystal which exhibits band gaps for elastic waves. … WebReconfigurable Phononic-Crystal Circuits Formed by Coupled Acoustoelastic Resonators
