Multi-Order Asymmetric Acoustic Metamaterials with Broad Bandgaps at Subwavelength Scales
Noise manipulation at the subwavelength scale remains a challenging problem. To obtain better broadband sound isolation within the subwavelength range, a class of asymmetric acoustic metamaterials (AAMs) based on rotation is proposed, and this class of AAMs can further improve subwavelength sound is...
