Confined phase singularities reveal the spin-to-orbital angular momentum conversion of sound waves
Ludovic Alhaïtz, Thomas Brunet, Christophe Aristégui +2
We identify an acoustic process in which the conversion of angular momentum between its spin and orbital form takes place. The interaction between an evanescent wave propagating at…
Experimental demonstration of negative refractionwith 3D locally resonant acoustic metafluids
Benoit Tallon, Artem Kovalenko, Olivier Poncelet +3
Negative refraction of acoustic waves is demonstrated through underwater experiments conducted at ultrasonic frequencies on a 3D locally resonant acoustic metafluid made of soft po…
Non-Reciprocal Thermal Material by Spatio-Temporal Modulation
Daniel Torrent, Olivier Poncelet, Jean-Chirstophe Batsale
The thermal properties of a material with a spatio-temporal modulation in both the thermal conductivity and the mass density are studied. The special configuration studied here con…
Using top graphene layer as sacrificial protection during dielectric atomic layer deposition
Xiaohui Tang, Nicolas Reckinger, Olivier Poncelet +5
We investigate the structural damage of graphene underlying dielectrics (HfO2 and Al2O3) by remote plasma-enhanced atomic layer deposition (PE-ALD). Dielectric film is grown on bil…
On the effective shear speed in 2D phononic crystals
A. A. Kutsenko, A. L. Shuvalov, A. N. Norris +1
The quasistatic limit of the antiplane shear-wave speed ('effective speed') in 2D periodic lattices is studied. Two new closed-form estimates of are derived by employing tw…
Spectral properties of a 2D scalar wave equation with 1D-periodic coefficients: application to SH elastic waves
A. A. Kutsenko, A. L. Shuvalov, A. N. Norris +1
The paper provides a rigorous analysis of the dispersion spectrum of SH (shear horizontal) elastic waves in periodically stratified solids. The problem consists of an ordinary diff…
Effective Willis constitutive equations for periodically stratified anisotropic elastic media
A. L. Shuvalov, A. A. Kutsenko, A. N. Norris +1
A method to derive homogeneous effective constitutive equations for periodically layered elastic media is proposed. The crucial and novel idea underlying the procedure is that the…
