Experimental validation of deep-subwavelength diffusion by acoustic metadiffusers

Ballestero, Eric; Jimenez, Noe; Groby, J. P.; Dance, Stephen; Aygün, H.; Romero-García, Vicente (American Institute of Physics, 2019-08-19)

[EN] An acoustic metadiffuser is a subwavelength locally resonant surface relying on slow sound propagation. Its design consists of rigidly backed slotted panels, with each slit being loaded by an array of Helmholtz ...
Scattering Evaluation of Equivalent Surface Impedances of Acoustic Metamaterials in Large FDTD Volumes Using RLC Circuit Modelling

Ballestero, Eric; Hamilton, Brian; Jimenez, Noe; Romero-García, Vicent; Groby, Jean Philippe; Aygun, Haydar; Dance, Stephen (MDPI AG, 2021-09)

[EN] Most simulations involving metamaterials often require complex physics to be solved through refined meshing grids. However, it can prove challenging to simulate the effect of local physical conditions created by said ...
