Based on the electromagnetic characteristics of photonic crystals, solving the maxwell equation, the application of transfer matrix method to solve electromagnetic wave propagation in one-dimensional photonic crystal transmittance characteristics, by changing the structure layer number of one-dimensional photonic crystal, material refractive index and thickness, layer number in the impact is not big changes of forbidden band width, the refractive index difference increases, the width of band gap has increased gradually, the two medium thickness has certain thickness difference than it did a broadband gap when the thickness is same.
