Photonic crystal is the refractive index lies between the electricity structure in the space periodic variation, its periodic and light wave length for identical magnitude. Photonic crystal also is called photonic band gap materials. Photonic crystals have many unique electromagnetic properties, such as the property of photonic band gap, the control to the spontaneous emission, the property of photonic bitable state, the property of photonic localization and so on. These properties have the extremely high practical application value in optics domain, and also attracted many experts to conduct the thorough research to it.Optics properties of the photonic crystals which constituted by ordinary optics medium is varied with incidence angle of electromagnetic wave, polarization direction, thickness of unit dielectric layer, difference of low-high dielectric film. While the variety can not be controlled very well in practical components. In 1968 former Soviet Union scientists Veselago once has done the pure theory research to the electromagnetic wave while the equivalent permittivity and the equivalent permeability for in the negative-index medium dissemination characteristic. From now on later has aroused people's interest regarding the negative refracting medium research, and in 2000 the people manufactured at the same time the equivalent permittivity and the equivalent permeability for the negative-index medium; But after the people have discovered the equivalent permittivity and the equivalent permeability respectively be the single-negative materials.The present paper the ordinary one-dimensional photonic crystals transmission matrix theory will carry on the deduction to revise, infers has been suitable in contains the negative refraction material the one-dimensional photonic crystals as well as one-dimensional photonic crystals with single-negative materials transmission matrix theory. The omni-directional photonic band gap and the Bragg gap characteristic, the photonic defect bureau territory characteristic and photonic crystals chromatic dispersion characteristic contained the negative-index material which after the revision transmission matrix fundamental research which the one-dimensional photonic crystals and one-dimensional photonic crystals with single-negative materials. In the research we discovered, in the photonic crystals has one kind to the electromagnetic wave incident angle, the electromagnetic wave polarization direction has the insensitive characteristic photonic band gap. At the...
