Analogy electromagnetism-acoustics: Validation and application to local impedance active control for sound absorption [PDF]
EUROPEAN PHYSICAL JOURNAL Applied Physics 4, 1 (10/1998) 95-100, 2007 An analogy between electromagnetism and acoustics is presented in 2D. The propagation of sound in presence of absorbing material is modeled using an open boundary microwave package. Validation is performed through analytical and experimental results. Application to local impedance active control for free field sound absorption is finally described.

Forget metamaterial: It does not improve sound absorption performance as it claims [PDF]
arXiv, 2023 The term `sub-wavelength' is commonly used to describe innovative sound-absorbing structures usually labeled as `metamaterials'. Such structures, however, inherently do not bring groundbreaking advancements. This study addresses the limitations imposed by the thickness criterion of Yang et al.
