Modeling Acoustic Metamaterials
Acoustic metamaterials enable the precise control of sound waves and are often used for efficient sound absorption and insulation as well as negative refraction, wave steering, and filtering. In testing these materials, multiphysics modeling and simulation are uniquely equipped to help engineers achieve a high level of control over their effective properties and to verify the required behavior of the structures.
This archived webinar begins with an overview of the physics-based considerations that need to be made when modeling metamaterials, then outlines the specific functionality available in the COMSOL Multiphysics® software that enables more efficient and accurate metamaterial development. This functionality includes periodic boundary conditions, fluid models for pressure acoustics, various options for thermoviscous acoustics modeling, and more.
The webinar showcases various modeling examples, including a phononic crystal, elastic coating, and anechoic coating, before concluding with a sonic crystal model demo.
