The recent review [Phys. Rev. Appl. 18, 027001 (2022)] has considered that the existing
schemes of nonreciprocal radiation are greatly limited by the narrow-operated bandwidth …

The tunable nonreciprocal radiation for near vertical incident light is investigated. The effect
is realized by placing a cascaded one-dimensional graphene and Weyl semimetal (WS) …

Violating Kirchhoff's radiation law through magneto-optical materials or spatiotemporal
(Floquet) metamaterials can open a new door for engineering thermal radiation by breaking …

Thermal nanophotonics has undergone a revolution in recent decades, benefiting from in-
depth studies in nano-optics and breakthroughs in nanotechnologies. The majority of …

The enhanced nonreciprocal radiation in grating structure for light under conical incidence is

The polarization-independent nonreciprocal radiation is highly demanded for controlling
light-matter interactions in tailoring and enhancing radiative heat transfer. An obvious …

A dual-channel thermal emitter, which is composed of an InAs layer atop an aluminum
grating backed with a continuous aluminum film, is proposed and studied. Two resonant …

According to Kirchhoff's radiation law, the spectral-directional absorptivity (α) and spectral-
directional emissivity (e) of an object are widely believed to be identical, which places a …
