Abstract :
We investigated the roles of wave impedance and refractive index in photonic crystals by means of analytical expressions for edges frequencies of a photonic bandgap (PBG) in a one-dimensional photonic crystal with magnetic and dielectric properties. The analytical expressions were derived when the optical thicknesses of layers are the same. The wave impedance governs the formation of PBG´s and the intensity of defect modes. Meanwhile, the position of PBG´s and the creation of defect modes are related to the refractive index
