UnverifiedIn thermal cloaks, thermal metamaterials need to possess a spatially varying thermal conductivity tensor, typically realized using alternating multilayer metal/dielectric structures or periodic hole structures.72% similarUnverifiedTraditional thermal invisibility schemes mostly rely on two-dimensional metamaterial surfaces and can only deceive thermal imagers from specific angles.71% similar
