We develop the fluctuational electrodynamics of metamaterials with hyperbolic dispersion and show the existence of broadband thermal emission beyond the black body limit in the near field. This arises due to the thermal excitation of unique bulk metamaterial modes, which do not occur in conventional media. We consider a practical realization of the hyperbolic metamaterial and estimate that the effect will be observable using the characteristic dispersion (topological transitions) of the metamaterial states. Our work paves the way for engineering the near-field thermal emission using metamaterials.
Our work led to a fundamental understanding of universal spin-momentum locking of light and near-field properties of light's polarization.
We introduced a universal right handed electromagnetic triplet consisting of electromagnetic momentum, decay and spin.
We have predicted the existence of a new topological phase of matter exhibiting photon spin-1 quantization.
