Phononic crystal saw
WebJan 10, 2024 · Both the SAW transducer as well as the phononic crystal were fabricated using optical photolithography on a (0 0 1)-oriented GaAs semi-insulating substrate. The phononic crystal waveguides were first produced using an array of circular holes with a four micron pitch and a 0.45 filling fraction on the photo mask. WebThis is an ideal book for those working with micro and nanotechnology, MEMS (microelectromechanical systems), and acoustic devices. Presents an introduction to the fundamentals and properties of phononic crystals. Discusses sonic and ultrasonic, hypersonic and planar, and three-dimensional phononic crystal structures.
