The transmittance, reflectance and absorption as a function of frequency are shown as the numerical results. In the first topic, we use single layer graphene sheet and two kinds of dielectrics for the simulation. And study the relationship between transmittance, reflectance, absorption and the different incident angle. The second theme is based on the photonic crystal with a defect layer. At first, we simulate the structure of photonic crystal without graphene in comparison with the structure with graphene layer, and then change the arrangement, the number of graphene layers and the different incident angles with TM and TE mode for our simulation. The transmittance as a function of frequency are shown as the numerical results. For the last topic, we use multilayer structure of graphene photonic crystal to do the simulation, we change the amount of graphene layer to find the structure with the best absorption. The transmittance, reflectance and absorption as a function of frequency are shown as the numerical results and the dominated incident wave mode is TM wave. So we can study the optical properties of graphene photonic crystal at high frequency region by these numerical results.光子晶體石墨烯光子能隙Photonic crystalsGraphenePhotonic band gap
