Band structure, Wiener bounds, and coupled surface plasmons in one dimensional photonic crystals

Recently metallic two and three dimensional photonic crystals (PCs) have been studied with the focus on using such structures in incandescent lighting and thermal photovoltaic applications. They exhibit a metallic band gap for low frequencies as well as structural band gaps. Especially the metallic band gap allows to block the infrared transmission respectively emission. In this letter we show that also the structural simpler one dimensional (1D) system has the same features; furthermore it builds an omnidirectional band gap for the Drude dispersion relation. For the case of a polaritonic system 1D PCs are able to exhibit angle of incidence as well as frequency dependent filter characteristics. The dispersion relation of surface plasmons, extending over adjacent layers is obtained. Propagating states must lie within the Wiener bounds.
