Derivation, verification and validation of a length correction factor for folded quarter-wavelength resonators
Acoustic metamaterials that consist of multiple λ/4-resonators in series or parallel can be tuned to realise high broadband absorption in a given frequency range. These resonators are often folded to obtain a structure with a (deep) sub-wavelength thickness, which allows an optimal use of the availa...
