TL;DR: A bilayer thermal cloak made of bulk isotropic materials is demonstrated, and it has been validated as an exact cloak and the robustness of this scheme is validated in both 2D (including oblique heat front incidence) and 3D configurations.

TL;DR: A viable recipe for controlling and manipulating heat signatures using thermal metamaterials to empower cloaking and camouflage in heat conduction is demonstrated.

TL;DR: In this paper, the authors cast a unified perspective on the control of heat transfer, based on which related studies can be considered as complementary paradigms toward manipulating physical parameters and realizing unprecedented phenomena in heat transfer using artificial structures, such as thermal conductivity in heat conduction, thermal emissivity in radiation, and properties related to multi-physical effects.

TL;DR: It is demonstrated that thermodynamic cloak can be achieved with homogeneous and finite conductivity only employing naturally available materials and the thermal localization inside the coating layer can be tuned and controlled robustly by anisotropy, which enables an incomplete cloak to function perfectly.

TL;DR: The design of an ultra-broadband infrared absorber based on metasurface is demonstrated and it is demonstrated that the absorption bandwidth can be greatly expanded by using two layers of metAsurface, i.e. dual-layered absorber.
