Abnormal topological refraction into free medium at sub-wavelength scale in valley phononic crystal plates
Linyun Yang, Kaiping Yu, Bernard Bonello +2
In this work we propose a topological valley phononic crystal plate and we extensively investigate the refraction of valley modes into the surrounding homogeneous medium. This phon…
Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present the realization of the topological valley-protected zero-order antisymmetric (A0) or symmetric (S0) and zero-order shear-horizontal (SH0) Lamb waves at different domain…
Valley and pseudospin-valley topologically protected edge states in symmetric pillared phononic crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present a symmetric double-sided pillared phononic crystals (PPnCs) that can emulate both quantum spin Hall effect (QSHE) and quantum valley Hall effect (QVHE) by solely imposin…
Autler-Townes splitting and acoustically induced transparency based on Love waves interacting with pillared meta-surface
Yuxin Liu, Abdelkrim Talbi, El Houssaine El Boudouti +3
Autler-Townes Splitting (ATS) and Electromagnetically Induced Transparency (EIT) are similar phenomena but distinct in nature. They have been widely discussed and distinguished by…
Gradient index phononic crystals and metamaterials
Yabin Jin, Bahram Djafari-Rouhani, Daniel Torrent
Phononic crystals and acoustic metamaterials are periodic structures whose effective properties can be tailored at will to achieve extreme control on wave propagation. Their refrac…
Interaction of Love waves with coupled cavity modes in a 2D holey phononic crystal
Yuxin Liu, Abdelkrim Talbi, Bahram Djafari-Rouhani +5
The interaction of Love waves with square array of pillars deposited on a cavity defined in a 2D holey phononic crystal is numerically investigated using Finite Element Method. Fir…
