Photonic crystals based on manganite-perovskite structure

The manganite-perovskite composites, as well as their lantanum doped analogs, demonstrating left handed media features, are quite perspective structures for design of electromagnetic materials of GHz and THz band. The propagation of electromagnetic waves in left-handed media (LHM) has been thoroughly investigated by many researchers, and various new phenomena have been discovered. In this manuscript, we present an experimental and theoretical study of one dimensional photonic crystals included a layer of manganite-perovskite into its primary cell.
