Abstract

The resonant tunneling properties of one-dimensional photonic crystal composed of alternately arranged PIM-PIM and PIMNIM are studied theoretically by using transfer matrix method. Transmittance and band structure properties of the structure are analyzed for different values of electric permittivity (±εi) and magnetic permeability (±µi) of the materials. The PIM layers are replaced by NIM layers (-ε2 and -µ2) in the periodic structure, we have found some peculiar band-gap structure and sharp transmittance properties. The transmission bands of the structure are found very sharp when refractive index and impedance of the NIM are very low. Such resonant tunneling property of the one dimensional photonic crystals containing NIMs may be utilized to make a very narrow filter.
