Research case study: Microphonic Crystals
"Our research area is the use of phononic crystals for surface acoustic waves at MHz frequencies. Surface acoustic waves are elastic waves that travel along the surface of a material and are widely used in electronic components for signal processing, sensing and increasingly for lab-on-a-chip applications. Phononic crystals can control the propagation of acoustic waves, enabling improved performance of existing device concepts as well as providing a route to more advanced applications."
