Magnetic-Field controlled radiative heat transfer

Abstract

The combination of magneto-optically active and resonant materials (e.g. plasmonic modes), makes it feasible to control optical properties using magnetic fields in connection to the excitation of resonances [1] (magnetoplasmonics). It has been shown that these nanostructures can be employed to modulate the propagation wavevector of SPPs [2], which allows the development of label free sensors with enhanced capabilities [3] or to enhance the magneto-optical response in isolated entities as well as films, in connection with a strong localization of the electromagnetic field [4,5]. Here we will show that they also play a crucial role in the active control thermal emission and the radiative heat transfer between objects in the near and far field regime [6-8].
