We study acoustic wave propagation in a waveguide loaded with two resonant side-branch channels. In the low frequency regime, one-dimensional models are derived in which the effect of the channels are reduced to jump conditions across the junction. When the separation distance is on the scale of the wavelength, which is the case that is usually considered, the jump conditions involve a single channel and acoustically induced transparency (AIT) occurs due to out-of-phase interferences between the…

Transmission gaps and Fano resonances in an acoustic waveguide: analytical model

A simple acoustic device consisting of two dangling side resonators grafted at two sites on a slender tube is designed possibly to obtain transmission stop bands (where the propagation of

Control of acoustic absorption in one-dimensional scattering by resonant scatterers

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, one-dimensional

Coupling of evanescent and propagating guided modes in locally resonant phononic crystals

In this paper, we present a combined theoretical, numerical and experimental study of acoustic wave propagation in 1D locally resonant phononic crystals made of acoustic resonators grafted onto a

Acoustic analogue of electromagnetically induced transparency and Autler–Townes splitting in pillared metasurfaces

Electromagnetically induced transparency (EIT) and Autler–Townes splitting (ATS) originating from multilevel atomic systems have similar transparency windows in transmission spectra which causes

Limits of slow sound propagation and transparency in lossy, locally resonant periodic structures

We investigate sound propagation in lossy, locally resonant periodic structures by studying an air-filled tube periodically loaded with Helmholtz resonators and taking into account the intrinsic

Transmission and absorption in a waveguide with a metamaterial cavity.

The reflection and transmission of acoustic waves along a waveguide of uniform width by a metamaterial cavity is considered. The metamaterial is comprised of a closely spaced array of micro-channels

Evanescent-wave tuning of a locally resonant sonic crystal

Locally resonant sonic crystals can support band gaps at low frequencies defined by resonances internal to the unit cell. Band gap frequencies are dictated by the choice of resonators and their

Scattering in a waveguide with narrow side channels

We consider an approximate solution based on matched asymptotic expansions to the problem of wave scattering by any number of narrow channels extending perpendicularly to one of the two straight

Optimized reactive silencers composed of closely-spaced elongated side-branch resonators.

Numerical results indicate that the minimum TL of the optimized silencers is reduced due to the destructive effect of the evanescent coupling from the resonators of the nearest side-branches, while the TL increases linearly with the number of the side- Branch resonators.

Experimental realization of a pillared metasurface for flexural wave focusing

A metasurface is an array of subwavelength units with modulated wave responses that show great potential for the control of refractive/reflective properties in compact functional devices. In this
