Metasurface Photodetectors [PDF]

Micromachines, 2021
Photodetectors are the essential building blocks of a wide range of optical systems. Typical photodetectors only convert the intensity of light electrical output signals, leaving other electromagnetic parameters, such as the frequencies, phases, and polarization states unresolved.

Magnetless reflective gyrotropic spatial isolator metasurface

New Journal of Physics, 2021
We present the concept of a magnetless reflective gyrotropic spatial isolator (RGSI) metasurface. This is a birefringent metasurface that reflects vertically polarized incident waves into a horizontally polarized waves, and absorbs horizontally polarized

Dynamic Hybrid Metasurfaces [PDF]

Nano Letters, 2021
Efficient hybrid plasmonic-photonic metasurfaces that simultaneously take advantage of the potential of both pure metallic and all-dielectric nanoantennas are identified as an emerging technology in flat optics. Nevertheless, post-fabrication tunable hybrid metasurfaces are still elusive. Here, we present a reconfigurable hybrid metasurface platform by

Low‐profile circularly polarized metasurface antenna with tailored reflection phase

Electronics Letters, 2021
A low‐profile metasurface antenna with circularly polarized radiation and tailored anisotropic reflection is proposed in this letter. The metasurface antenna composed of excitation structure (microstrip line with coupling slot) and a metasurface layer ...

Design of dual-wavelength polarization control metasurface lens

Xibei Gongye Daxue Xuebao, 2022
With the rapid development of modern optics, optical elements have become an indispensable part of an optical system. A metasurface is a nanostructure composed of arrays of sub-wavelength scatterers and is widely used due to its simple structure, thin ...

Metasurfaces and Optimal transport

The SMAI Journal of computational mathematics, 2022
This paper provides a theoretical and numerical approach to show existence, uniqueness, and the numerical determination of metalenses refracting radiation with energy patterns. The theoretical part uses ideas from optimal transport and for the numerical solution we study and implement a damped Newton algorithm to solve the semi discrete problem.

Electromagnetic Metasurfaces and Reconfigurable Metasurfaces: A Review [PDF]

Frontiers in Physics, 2021
Metamaterial is a kind of material/structure that is artificially designed and has exceptional electromagnetic properties and/or other physical properties, not found in nature. A class of electromagnetic metamaterial with only one or a few layers of periodic or aperiodic arranged cell structures in the direction of electromagnetic waves propagation can

Bamboo-Slip-Inspired Conformal Reconfigurable Metasurfaces. [PDF]

Adv Sci (Weinh)
Bamboo‐slip‐inspired conformal reconfigurable metasurface system. The structure is mainly composed of three parts, which are conformal metasurface, pattern reconfigurable antenna, and control components (such as Field Programmable Gate Array (FPGA)). Conformal metasurfaces draw inspiration from the design of ancient Chinese bamboo slips.
