Polarization-controlled non-Hermitian metasurfaces for ultra-sensitive terahertz sensing
Xintong Shi, Hai Lin, Tingting Liu +8
Non-Hermitian systems offer significant advantages in sensor design, especially at the exceptional points. However, the extreme sensitivity near these points poses great challenges…

Coherent perfect absorber and laser induced by directional emissions in the non-Hermitian photonic crystals
Zhifeng Li, Hai Lin, Rongxin Tang +5
In this study, we propose the application of non-Hermitian photonic crystals (PCs) with anisotropic emissions. Unlike a ring of exceptional points (EPs) in isotropic non-Hermitian…
