“…with i = j = k, ε 0 the vacuum permittivity, E i (ω) the ith Cartesian component of the electric field at ω, and χ (2) ijk the second-order susceptibility, which in the case of AlGaAs was set to 200 pm V −1 [30]. In our simulations the dielectric nanodiscs were the sole sources of SH since both the LC and the AlOx substrate have negligible χ (2) [31].…”

“…All-dielectric metasurfaces are attracting increasing interest from the scientific community for optical wavefront manipulation [1][2][3]. The possibility of controlling the phase of the light scattered by each unit of the metasurface and the lossless nature of the optical resonances in high refractive index dielectric nanostructures are key assets [4,5].…”

“…Similar to plasmonic counterparts, all‐dielectric anisotropic meta‐atoms composed of high‐refractive index materials can be used to construct compact polarization converters. [ 10 ] In particular, due to the existing multipole Mie resonances that are spectrally overlapped at a single frequency or spectrum range with similar or identical strengths, [ 10,33–35 ] independent and complete phase and polarization control of transmitted fields is possible. Meanwhile, the transmission efficiency can be boosted to a large extent by suppressing the reflection.…”

“…Computing metasurfaces are two-dimensional artificial nanostructures capable of performing mathematical operations on the input electromagnetic field ( Silva et al., 2014 ; Pors et al., 2015 ; Hwang and Davis, 2016 ; Zhu et al., 2017 ; Lee et al., 2017 ; Zangeneh-Nejad et al., 2020 ; Li et al., 2021 ; Jin et al., 2021 ; Yung et al., 2022 ; He et al., 2022 ; Fu et al., 2022 ). The spatial differentiation operations based on computing metasurfaces have been applied for all-optical image processing, especially for edge detection ( Dong et al., 2018 ; Kwon et al., 2018 ; Zhou et al., 2019 , 2020 , 2021 ; Momeni et al., 2019 ; Huo et al., 2020 ; Liu et al., 2020 ; Wesemann et al., 2021 ; Solntsev et al., 2021 ; Yang et al., 2021 ). In recent years, because of the sensitivity to changes in physical parameters of the system, weak-value amplification techniques have been proposed for the chiral sensing ( Rhee et al., 2013 ; Wang et al., 2020 ).…”
