What this work contributes
Demonstrates nonreciprocal mid-infrared scattering from a graphene-based metasurface driven by space-time modulation. Theory relates the measured scattering asymmetry to unequal thermal absorption and emission channels.
Where the evidence stops
The measured result is scattering nonreciprocity. Thermal-emission implications are inferred through the accompanying theory; this is not a measured thrust result, and the modulation drive belongs in energy accounting.
