Abstract:
By using the transfer matrix,the band structures,defect mode and field propagation characteristics of one-dimensional photonic crystals composed of single-negative (SNG) material are studied. It is shown that this structure possesses a new type of photonic gap which is insensitive to the incident angle and the light polarizations,as well the change of scale length. When a normal dielectric defect layer is inserted,the defect mode is insensitive to the angle of incidence,but the electro-magnetic field in the...
