Simulating Band Gaps and Scattering in Phononic Crystals with COMSOL Multiphysics® - Archived
Phononic crystals, a subclass of acoustic metamaterials, have had a large number of applications in microfluidic devices and as waveguides, collimators, isolators, and surface and bulk acoustic wave devices. Designing these crystals requires understanding the dispersion and scattering characteristics. The dispersion diagrams allow for a direct estimation of frequency band gaps and transmittance, which is a scattering parameter, and provides the percentage of wave energy passing through the medium.
In this webinar, Dr. Chandraprakash will talk about building models in COMSOL Multiphysics® to estimate the band gaps, reflectance, and transmittance. Examples will be provided from his recent work on two- and three-dimensional models and highlight the need for validation.
