Towards compact high-frequency nonreciprocal devices using nanoplasma-switched time-varying metasurfaces
Mikhail Sidorenko, Jin Zhang, Xuchen Wang +3
Time-modulated systems have received growing interest in recent years. They allow us to tailor effects, such as frequency conversion, single-direction propagation, etc. For the mic…
Symmetry-Empowered Through-Barrier Sensing in Complex Media
Shuai S. A. Yuan, Zhazira Zhumabay, Viktar Asadchy +1
Symmetry strongly impacts wave transport in complex media. In this Letter, we demonstrate that the phenomenon of symmetry-induced through-barrier transmission enhancement enables q…
Realization of the Tellegen Effect in Resonant Optical Metasurfaces
Shadi Safaei Jazi, Ihar Faniayeu, Rafael Cichelero +5
The nonreciprocal magnetoelectric effect in Tellegen materials enables exotic phenomena such as axion-modified electrodynamics and fosters the development of magnet-free nonrecipro…
Strong Mode Coupling via Quasi-Bound States in the Continuum in Bianisotropic Metasurfaces
Luis Manuel Máñez-Espina, Bahman Amrahi, Viktar Asadchy +1
Electromagnetic mode coupling plays a key role in many resonant effects in nanophotonics. This coupling is also responsible for the appearance of bianisotropy, where electric and m…
Giant bias-free nonreciprocity for unpolarized light via synthetic motion
L. M. Máñez-Espina, B. Amrahi, I. Faniayeu +4
Reciprocity breaking at optical frequencies typically relies on bulky magnets, dynamic modulation, or nonlinearities, all of which hinder chip-scale integration and the handling of…
