Journal ArticleDOI
Ultrathin pancharatnam-berry metasurface with maximal cross-polarization efficiency.
Xumin Ding,Francesco Monticone,Kuang Zhang,Lei Zhang,Dongliang Gao,Shah Nawaz Burokur,André de Lustrac,Qun Wu,Cheng-Wei Qiu,Andrea Alù +9 more
TL;DR: The planar metalens proposed empowers significant reduction in thickness, versatile focusing behavior, and high transmission efficiency simultaneously, showing a remarkable improvement compared with earlier ultrathin metasurface designs with less than 5% coupling efficiency.
Journal ArticleDOI
Independent phase modulation for quadruplex polarization channels enabled by chirality-assisted geometric-phase metasurfaces
Yueyi Yuan,Kuang Zhang,Badreddine Ratni,Qinghua Song,Xumin Ding,Qun Wu,Shah Nawaz Burokur,Patrice Genevet +7 more
TL;DR: The concept of chirality-assisted phase is introduced as a degree of freedom, which could decouple the two co-polarized outputs, and thus be an alternative solution for designing arbitrary modulated-phase metasurfaces with distinct wavefront manipulation in all four CP output channels.
Journal ArticleDOI
Phase-engineered metalenses to generate converging and non-diffractive vortex beam carrying orbital angular momentum in microwave region
Kuang Zhang,Yueyi Yuan,Dawei Zhang,Xumin Ding,Badreddine Ratni,Shah Nawaz Burokur,Manjun Lu,Kun Tang,Qun Wu +8 more
TL;DR: The proposed method provides an efficient approach to control the radius of vortex beam carrying OAM mode in microwave wireless applications for medium-short range distance.
Journal ArticleDOI
A Fully Phase-Modulated Metasurface as An Energy-Controllable Circular Polarization Router.
Yueyi Yuan,Shang Sun,Yang Chen,Kuang Zhang,Xumin Ding,Badreddine Ratni,Qun Wu,Shah Nawaz Burokur,Cheng-Wei Qiu +8 more
TL;DR: A general method is proposed to construct phase‐modulated metasurfaces for implementing functionalities separately in co‐ and cross‐polarized output fields under circularly polarized (CP) incidence, which is impossible to achieve with solely a geometric phase.
Journal ArticleDOI
Leaky-Wave Antennas Based on Noncutoff Substrate Integrated Waveguide Supporting Beam Scanning From Backward to Forward
Yue-Long Lyu,Xiao-Xin Liu,Peng-Yuan Wang,Daniel Erni,Qun Wu,Cong Wang,Nam-Young Kim,Fanyi Meng +7 more
TL;DR: In this paper, the authors proposed an approach to realize substrate integrated waveguide (SIW)-based leaky-wave antennas (LWAs) supporting continuous beam scanning from backward to forward above the cutoff frequency.
