Abstract

Magnetic polariton, which is coupling of electromagnetic waves with nanostructures by excitation of artificial magnetic resonance in the optical and infrared region, has been recently studied extensively. Similar to surface plasmon or phonon polariton, magnetic polartion could achieve strong spectral selectivity with carefully designed metamaterials, while the unique characteristics including strongly localized energy and omnidirectionality make it suitable for energy related applications such as thermal energy harvesting and conversion, radiative cooling, coherent thermal source, and optical data storage. This chapter comprehensively reviews recent theoretical and experimental progresses in spectral control of thermal radiation with magnetic polaritons such as selective infrared emission, selective optical absorption, selective transmission, and coupling with 2D and tunable materials. Potential impacts on practical applications will be discussed, and the effect of magnetic polariton on near-field radiative heat transfer will be highlighted.
