WebSep 14, 2015 · Phononic crystals are artificial periodic structures that can alter efficiently the flow of sound, acoustic waves, or elastic waves. They were introduced about twenty years ago and have gained... WebA photonic crystal corresponds to a periodic dielectric function ε(~x) = ε(~x + R~ i) for some primitive lattice vectors R~ i (i = 1,2,3 for a crystal periodic in all three dimensions). In this case, the Bloch-Floquet theorem for periodic eigenproblems states that the solutions to Eq. (1) can be chosen of the form H~ (~x) = ei~k·~xH~ mhw kirin armor set

WebApr 29, 2024 · This work proposes a method to design phononic crystal reflectors efficiently. For a prove of concept, a kind of quasi-surface acoustic wave and bulk acoustic wave (SAW/BAW) hybrid-coupled resonator with phononic crystal as reflectors is studied. The proposed design is implemented on the aluminum nitride (AlN) thin film with a high … WebThis research is funded by the Air Force Office of Scientific Research under grant number 20RXCOR058.
