Abstract

Recent studies show that magnetic polaritons (MPs) are responsible for the extraordinary optical transmission in subwavelength periodic structures. However, the role of MP in double-layer nanoslit arrays has not been fully understood. This paper elucidates how MPs influence the radiative properties of nanoslit arrays at both normal and oblique incidences using the rigorous coupled-wave analysis. The existence of MPs is further confirmed by an equivalent LC circuit model. The effects of geometric parameters and lateral displacement on the resonance conditions are also investigated, and possible ways of tailoring the radiative properties of nanostructures for energy-harvesting applications are suggested.
