To develop modified finite‐difference time‐domain (M‐FDTD) algorithm with magnetized plasma medium, constitutive equation between current density vector and electric field strength vector is first transformed into s‐domain for decoupling, and then transformed back into time domain so that the FDTD iteration equations can be easily obtained in discrete time domain.Then the reflection coefficients with plasma slab calculated by the proposed M‐FDTD algorithm are compared with analytical to show the validity of our technique. Finally, the M‐FDTD algorithm is applied to calculate the reflection and transmission coefficients of plasma photonic crystal of different plasma parameters. © 2011 Wiley Periodicals, Inc.
