As discussed by Dhiraj Sinha in article number 1800360 , interaction between instantaneous charges appearing on the surface of a metamaterial structure and external electromagnetic waves result in radiation. Thus, metamaterials can no longer remain invisible under non‐equilibrium thermal fluctuations. The figures illustrate a spherical metamaterial structure with thermally induced charges along the edges and the Gaussian form of vector magnetic potential generated as a consequence of thermally induced radiation.
