▎ 摘　　要

NOVELTY - The method involves establishing electromagnetic wave time-domain finite difference equation based on generalized layer transmission condition. A wide graphene material of an electric polarizability tensor and a magnetic polarizability tensor is extracted. The electric polarizability tensor and the magnetic polarizability tensor are fitted based on generalized layer transmission condition and finite-difference time-domain method. Polarization current density and polarization magnetic flow density are obtained on electric field intensity and magnetic field intensity. Differential iteration is performed. The electric field intensity is calculated based on a calculation domain and the magnetic field intensity using discrete Fourier transform calculation to obtain reflection coefficient and transmission coefficient. USE - Method for analyzing electromagnetic reflection and transmission characteristics of graphene under broadband. ADVANTAGE - The method enables saving time and memory required for analyzing the graphene electromagnetic reflection and transmission characteristics with high flexibility and high effectiveness. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for analyzing electromagnetic reflection and transmission characteristics of graphene under broadband.
