Compound symmetries and double antisymmetry groups in linear time-invariant photonic systems
Yunrui Wang, Shiyu Li, Cheng Guo
Symmetry is fundamental to photonic systems. External (spatial) symmetries and internal symmetries---Lorentz reciprocity, energy conservation, and time-reversal symmetry---constrai…

Probability Distribution for Coherent Transport of Random Waves
Yunrui Wang, Cheng Guo
We establish a comprehensive probability theory for coherent transport of random waves through arbitrary linear media. The transmissivity distribution for random coherent waves is…

Observation of Fully Flat Bands in a Photonic Dipolar Kagome Lattice
Han-Rong Xia, Ziyao Wang, Yunrui Wang +2
Flat bands, characterized by zero group velocity and strong energy localization, enable interaction-enhanced phenomena across both quantum and classical systems. Existing photonic…
