Abstract
An anti-reflective acoustic diffusion device is provided by a group of irregularly dimensioned diffusing elements positioned on an acoustic wave substrate end that diffuse the SAW and eliminate unwanted acoustic reflections from the end of the substrate. The irregularly dimensioned diffusing elements are substantially irregular in size, shape, composition, and location and provide the desired diffusion into a nearly uniform distributed acoustic energy with a random phase. The anti-reflective acoustic diffusion device can be used with SAW, BAW or multiple acoustic wave configurations. This invention also encompasses an anti-reflective acoustic diffusion system and methods for diffusing acoustic reflections with anti-reflective acoustic diffusing elements.
