Dual-polarization control of broadband nonreciprocal thermal radiation by combining local and nonlocal metasurfaces
Shuang Xia, Mengqi Liu, Wenjian Wan +10
Nonreciprocal thermal radiation offers a route to decouple spectral directional absorptivity and emissivity, thereby enabling new paradigms in thermal-photonic systems. However, in…

Unlock giant nonreciprocity via multi-valued behavior of non-Hermitian zero-index materials
Yang Li, Yueyang Liu, Yucong Yang +13
Although Einstein's field equations are time-independent, the multivalued feature of the horizon of a blackhole naturally enables the one-way transmission, leading to the strong ar…
