Mie Resonator Acoustic Metamaterial Designer

Computes the transmission loss for a Mie resonator acoustic metamaterial in a duct

This app computes the transmission loss of a labyrinthine-style Mie resonator acoustic metamaterial array to be used in a duct of the same radius as the outer radius of the metamaterial. All calculations and methods were acquired from Composite Acoustic Metamaterial for Broadband Low-Frequency Acoustic Attenuation by Chen et al in Physical Review Applied. This paper discusses the application of a Mie resonator metamaterial in conjunction with a Helmholtz resonator array for noise control in a duct. However, this app just considers the Mie resonator array. App's calculations give good agreement with the graph presented in the paper in Figure 2a.

Current Features:

• Computes the sound transmission loss of a Mie resonator array acoustic metamaterial
• User can modify the outer radius, path width, wall thickness, resonator height, curling number, and number of unit cells
• Variable frequency range for computation
