Phononic crystal saw
WebReconfigurable Phononic-Crystal Circuits Formed by Coupled Acoustoelastic Resonators 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. …
