Papers
Simultaneous control of the scattering amplitude, phase, and polarization with nonlocal metasurfaces
Adam C. Overvig,Andrea Alù,Yoshiaki Kasahara +2 more
- 17 Mar 2023
TL;DR: In this paper , the authors report the finding of a polarization-agnostic geometric phase, and experimentally establish that it applies even to linear polarization states, which opens opportunities in augmented reality, secure optical communications and nonlinear and quantum optics.
Generation and resilient routing of helical lattice vibrations in mid-infrared topological metasurfaces
Sriram Guddala,Filipp E. Komissarenko,Svetlana Kirjushechkina,Anton Vakulenko,Mengyao Li,Vinod M. Menon,Andrea Alù,Alexander B. Khanikaev +7 more
- 03 Oct 2022
TL;DR: In this article , the topological properties of photonic modes are transcribed to the in-plane lattice vibrations (phonons) supported by hexagonal boron nitride (hBN).
Coherent Control of Scattering in Non-Hermitian PT-Symmetrical Systems
Zarko Sakotic,Alex Krasnok,Norbert Cselyuszka,Nikolina Jankovic,Andrea Alù +4 more
- 01 Sep 2019
TL;DR: In this paper, the authors demonstrate how the concept of coherent excitation can pave the way to light scattering control in an extreme fashion in non-Hermitian PT-symmetrical systems supporting an embedded eigenstate.
Scattering and radiation singularities in epsilon-near-zero structures
Francesco Monticone,Andrea Alù +1 more
- 01 Jun 2016
TL;DR: In this article, the extreme and singular electromagnetic response of epsilon-near-zero (ENZ) structures was studied, and it was shown that ENZ-dielectric-ENZ multilayers can be designed to support singularities in their scattering spectrum, known as embedded eigenstates, which can be exploited for extreme light trapping in open systems, as well as for enhanced sensing.
