In this study, a composite meta-absorber with a flexible size is proposed, and a genetic
algorithm is used to optimize the geometric dimensions under normal incidence and free …

Perfect, broadband and asymmetric sound absorption is theoretically, numerically and
experimentally reported by using subwavelength thickness panels in a transmission …

Using the concepts of slow sound and critical coupling, an ultra-thin acoustic metamaterial
panel for perfect and quasi-omnidirectional absorption is theoretically and experimentally …

Perfect absorption is an interdisciplinary topic with a large number of applications, the
challenge of which consists of broadening its inherently narrow frequency-band …

The reflection of sound of frequency below 1 kHz, by a rigid-backed structure that contains
sub-wavelength resonators is studied in this work. In particular, only single mode reflected …

We theoretically and experimentally report subwavelength resonant panels for low-
frequency quasiperfect sound absorption including transmission by using the accumulation …

Dans cette revue, nous présentons des résultats sur l'absorption acoustique parfaite sub-
longueur d'onde faisant appel à des métamatériaux acoustiques avec des résonateurs …

We experimentally report perfect acoustic absorption through the interplay of the inherent
losses and transparent modes with high Q factor. These modes are generated in a two-port …

We combine numerical simulations and experiments to design a new class of reconfigurable
waveguides based on three-dimensional origami-inspired metamaterials. Our strategy …

From being an unfavorable consequence to finding itself as the intended imaginary part of a
non-Hermitian system, loss has truly emerged as more of a friend than a foe in the context of …
