A nonreciprocal and tunable active acoustic scatterer
Anis Maddi, Gaelle Poignand, Vassos Achilleos +2
A passive loudspeaker mounted in a duct acts as a reciprocal scatterer for plane waves impinging on either of its sides. However, the reciprocity can be broken by means of an asymm…
Robustness of perfect transmission resonances to asymmetric perturbation
Ioannis Kiorpelidis, Panayotis Kalozoumis, Georgios Theocharis +3
We investigate the impact of asymmetric perturbations on the perfect transmission resonances (PTRs) of one-dimensional finite periodic systems. With no perturbations, the scatterin…
Transient amplification in stable Floquet media
Ioannis Kiorpelidis, Fotios K. Diakonos, Georgios Theocharis +1
The Mathieu equation occurs naturally in the description of vibrations or in the propagation of waves in media with time-periodic refractive index. It is known to lead to exponenti…
Existence and characterization of edge states in an acoustic trimer Su-Schrieffer-Heeger model
I. Ioannou Sougleridis, A. Anastasiadis, O. Richoux +4
We report on a direct mapping of acoustic slender waveguides to the one dimensional trimer Su- Schrieffer-Heeger model, with neither chiral nor mirror symmetry. Importantly, we can…
