Phononic crystal saw
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. … WebJan 1, 2016 · The phononic crystal sensor is therefore fundamentally different to the majority of current chemical sensors. It has at least three significant consequences. First, …
