Inverse design of exceptional points in a single-resonance two-port network
Y. F. Li, Biao Chen, Y. Wu +3
Exceptional points (EPs) in non-Hermitian photonic systems enable unconventional control of wave amplitude and phase. However, identifying the EPs in a multidimensional parameter s…
Anisotropic non-Hermitian skin effect in a two-dimensional Lieb photonic crystal
Zhi-Kang Xiong, Tianlei Wen, Y. Liu +2
In this contribution paper, we construct a two-dimensional non-Hermitian (NH) photonic crystal (PhC) to prototype its anisotropic non-Hermitian skin effect (NHSE) for experimental…
Non-Hermitian curved space via inverted wave equation
C. Zhang, M. Ikram, Y. Liu +2
Directly determining graded materials from prescribed wave amplitude and phase is an inverse-design method developed following transformation optics (TO), which enables reflectionl…
A decomposition for transverse spins in structured vector fields
Zhi-Kang Xiong, Zhen-Lai Wang, Y. Liu +2
Classical vector waves can possess intricate spin angular momenta (SAM), which are \emph{perpendicular} to the propagation direction, as revealed by the recent recognition of surpr…
