Roadmap on superoscillations

M Berry, N Zheludev, Y Aharonov, F Colombo… - Journal of …, 2019 - iopscience.iop.org
Superoscillations are band-limited functions with the counterintuitive property that they can
vary arbitrarily faster than their fastest Fourier component, over arbitrarily long intervals …

Reflectionless programmable signal routers

J Sol, A Alhulaymi, AD Stone, P Del Hougne - Science Advances, 2023 - science.org
We demonstrate experimentally that reflectionless scattering modes (RSMs), a generalized
version of coherent perfect absorption, can be functionalized to perform reflectionless …

Perfect absorption and phase singularities in plasmon antenna array etalons

A Berkhout, AF Koenderink - ACS Photonics, 2019 - ACS Publications
We present an interferometrically resolved study of the amplitude and phase response of
plasmon array etalons composed of a reflective surface with a metasurface of resonant …

Transverse shifts and time delays of spatiotemporal vortex pulses reflected and refracted at a planar interface

M Mazanov, D Sugic, MA Alonso, F Nori, KY Bliokh - Nanophotonics, 2022 - degruyter.com
Abstract Transverse (Hall-effect) and Goos–Hänchen shifts of light beams reflected/refracted
at planar interfaces are important wave phenomena, which can be significantly modified and …

Spin-Hall effect of light at a tilted polarizer

KY Bliokh, C Prajapati, CT Samlan, NK Viswanathan… - Optics letters, 2019 - opg.optica.org
We describe the spin-Hall effect of light (as well as the angular Goos-Hänchen effect) at a
tilted linear-dichroic plate, such as a usual linear polarizer. Although the spin-Hall effect at a …

Measurement of the magnetic properties of thin films based on the spin Hall effect of light

T Li, Q Wang, A Taallah, S Zhang, T Yu, Z Zhang - Optics Express, 2020 - opg.optica.org
Using the spin Hall effect of light, this work proposes a measurement technique of the
