Black-Hole Ringdown from Photon-Sphere Modes in an Elastic Analogue
Jiaoqing Wang, Chenni Xu, Sophia Purow +2
Quasinormal modes (QNMs) govern the ringdown of black holes, yet their physical origin and experimental accessibility remain limited. Here we create an elastic analogue of a black…
Space-Time Elastic Metamaterials for Zero-Frequency and Zero-Wavenumber Bandgaps
Brahim Lemkalli, Alaa Ali, Qingxiang Ji +5
We create wave-matter space-time metamaterials using optical trapping forces to manipulate mass-spring chains and create zero-frequency and zero-wavenumber band gaps: the bosonic n…
W-shaped Broadband Attenuation of Longitudinal Waves through Composite Elastic Metamaterial
B. Lemkalli, K. K. Dudek, M. Kadic +4
We investigate a composite elastic meta-slab with exceptional transmission properties, particularly the presence of a W-shaped bandgap. A comprehensive study, utilizing experimenta…
Photonic crystal carpet: Manipulating wave fronts in the near field at 1550 nm
G. Scherrer, M. Hofman, W. Śmigaj +9
Ground-plane cloaks, which transform a curved mirror into a flat one, and recently reported at wavelengths ranging from the optical to the visible spectrum, bring the realm of opti…
