Breaking the limitation of polarization multiplexing in optical metasurfaces with engineered noise
Science, 2023Noise is usually undesired yet inevitable in science and engineering. However, by introducing the engineered noise to the precise solution of Jones matrix elements, we break the fundamental limit of polarization multiplexing capacity of metasurfaces that

Chiral emission from resonant metasurfaces
Science, 2022Ultracompact sources of circularly polarized light are important for classical and quantum optical information processing. Conventional approaches for generating chiral emission are restricted to excitation power ranges and fail to provide high-quality ...

Metasurface design constraints in Metasurface-based Virtual absorbers
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021In this contribution, we will present our investigation on design limits of the metasurfaces to be used for enabling virtual absorbing in metasurface-based virtual absorbers. To reach this goal, we analytically identify the conditions under which a properly modulated monochromatic plane wave can be virtually absorbed by the system, deriving the ...

Multicolor and 3D Holography Generated by Inverse‐Designed Single‐Cell Metasurfaces
Advances in Materials, 2022Metasurface‐generated holography has emerged as a promising route for fully reproducing vivid scenes by manipulating the optical properties of light using ultra‐compact devices. However, achieving multiple holographic images using a single metasurface is

Metasurfaces for quantum photonics
Nature Photonics, 2020Rapid progress in the development of metamaterials and metaphotonics allowed bulky optical assemblies to be replaced with thin nanostructured films, often called metasurfaces, opening a broad range of novel and superior applications of flat optics to the

This chapter reports design and analysis methods for planar antennas based on modulated metasurfaces (MTSs). These antennas transform a surface wave (SW) into a leaky wave by means of the interaction with a MTS having a spatially modulated equivalent impedance.
