Abstract
A novel graphene photonic crystal structure is proposed and designed in this paper; each unit period is composed of graphene, metal, and magnesium fluoride. We investigate the optical properties of this structure in the visible to near-infrared range by means of finite-difference time-domain method. We examined the influence of structural parameters (metal material, thickness, period number, etc.) on the optical response of the structure and found that it can be transparent in visible range and can shield most of the near-infrared rays. As a result, the proposed graphene photonic structure enables potential applications in selective near-infrared shielding material.
