The two-dimensional(2-D) photonic crystal with layered composite medium cylinder was proposed,and effect of the refraction indexes,thicknesses,layers and composition sequences on the transmittance of the 2-D photonic crystal composed of multilayered composite medium was studied by means of the finite-difference time-domain method.The numerical results show that the forbidden band width and the position of central frequency in 2-D photonic crystal with multilayered medium are different from those composed of single medium.Therefore,the adjustable factors for 2-D photonic crystal with multilayered medium are more than those with single medium in application and the above theory can be as a theoretical basis on 2-D photonic crystal design.
