Active Times for Acoustic Metamaterials

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

Initially proposed to achieve strong noise isolation levels beyond the mass-density law, acoustic metamaterials (AMMs) have now overturned the conventional views in all aspects of sound propagation and manipulation. In fact, within the last two decades, th ...

Acoustic birefringence via non-Eulerian metamaterials

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

The recently proposed concept of metamaterials has opened exciting venues to control wave-matter interactions in unprecedented ways. Here, we demonstrate the relevance of metamaterials for inducing acoustic birefringence, a phenomenon which has already fou ...

Acoustic Supercoupling in a Zero-Compressibility Waveguide

Seyyed Hussein Seyyed Esfahlani

Funneling acoustic waves through largely mismatched channels is of fundamental importance to tailor and transmit sound for a variety of applications. In electromagnetics, zero-permittivity metamaterials have been used to enhance the coupling of energy in a ...

Robust wave transport at subwavelength scale with chiral metamaterials

Romain Christophe Rémy Fleury, Nadège Sihame Kaïna, Bakhtiyar Orazbayev

Rapid progress in all types of communication systems imposes each time more strict requirements on the communication devices, requiring having the overall device's size as small as possible, but also increasing the demands on the robustness of the transmis ...

The invisibility via anomalous localized resonance of a source for electromagnetic waves

Hoài-Minh Nguyên

We investigate the invisibility via anomalous localized resonance of a general source in anisotropic media for electromagnetic waves. To this end, we first introduce the concept of doubly complementary media in the electromagnetic setting. These are media ...
