A novel finite-difference time-domain(FDTD) method is proposed to analyse electromagnetic wave transmission characteristics of magnetized plasma. The constitutive equation between current density vector and electric field strength vector is tranformed into s-domain by the principle of Laplace transform, and the inverse Laplace transform is adopted for the explicit equations between them in time-domain. Finally through exponential time stepping, the FDTD iteration equations are obtained, which can be easily solved in discrete-time-domain. By these techniques, the difficulty, that the two components of the current density vector can not be discreted because of their coupling in the constitutive equation, is solved. Reflection coefficient of anisotropic plasma slab is calculated using this me
