Twist Bilayer Photonic slab's Angle-DependentGuided Resonance Analysis based on Multiple Scattering
Wenzhu Xie, Yan Wang, Jingxuan Chen +4
We present an analysis of the transmission spectra of the twisted bilayer photonic slabs using a modified rigorous coupled wave (RCWA) analysis, where the evanescent bases are repl…

Symmetry breaking of Pancharatnam-Berry phase using non-axisymmetric meta-atoms
Baifu Zhang, Yan Wang, Zhixing Huang +3
The Pancharatnam-Berry (PB) phase in metasurfaces obeys the symmetry restriction, according to which the PB phases of two orthogonal circularly polarized waves are the same but wit…
