Thermal radiation is nominally broadband, incoherent, and isotropic, so controlling the spectral, temporal, and directional characteristics of thermal emission is an important frontier in imaging and chemical fingerprinting. The use of thermal metasurfaces, whose emission properties can be finely tailored, has recently become of great interest. Here we theoretically demonstrate the thermal emission of a metasurface arising from the coupled emission from a plasmonic mode in graphene nanoribbons and the guided mode resonance of a 1D photonic crystal. We also discuss the utility of a computationally cheap approach based on coupled-mode theory to model the device scattering characteristics.
