Effects of off-diagonal permittivity terms on polarization singularities in anisotropic grating system
Siyu Lei, Ze-Huan Zheng, Qilin Duan +4
The evolutions of polarization singularities, including bound states in the continuum (BICs) and circularly polarized states (C points), are usually realized by tuning the geometri…
