Metasurface design constraints in Metasurface-based Virtual absorbers

2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021
In 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 ...

Metasurface Antennas

2017
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.

Optoelectronic metasurfaces

Metamaterials, Metadevices, and Metasystems 2017, 2017
Plasmonic metasurfaces offer a new paradigm for the design of optoelectronic devices. We discuss nanoscale device ideas that exploit the optical field enhancement and confinement provided by such metasurfaces to achieve performance benefits.

Coding Acoustic Metasurfaces

Advanced Materials, 2016
Coding acoustic metasurfaces can combine simple logical bits to acquire sophisticated functions in wave control. The acoustic logical bits can achieve a phase difference of exactly π and a perfect match of the amplitudes for the transmitted waves. By programming the coding sequences, acoustic metasurfaces with various functions, including creating ...

Multiresonant Nonlocal Metasurfaces

Nano Letters, 2023
Optical metasurfaces supporting localized resonances have become a versatile platform for shaping the wavefront of light, but their low quality (Q-) factor modes inevitably modify the wavefront over extended momentum and frequency space, resulting in limited spectral and angular control.

Chiral metasurface optomechanics

Conference on Lasers and Electro-Optics, 2019
We report on mechanical action on light polarization, and its back-action effect, in a chiral metasurface. Our thin-film nanostructured semiconductor device may prove of relevance for fast polarization state generation and detection.
