Learn how to use COMSOL Multiphysics^® and the add-on Acoustics Module to simulate acoustic metamaterials in this archived webinar.

The presentation gives an introduction to the Acoustics Module and shows how to use the Floquet boundary conditions to model repeating structures to find their band gaps. During the demo, we show you how to model a sonic crystal.

Tip: Download the Sonic Crystal tutorial model from the Application Gallery.
