Abstract
For the Symplectic Finite-difference Time-domain (SFDTD) method has higher accuracy and lower numerical dispersion, it is better than the traditional FDTD method. Although the SFDTD method has a lot of advantages, it cannot be used on the moving medium in previous research. Therefore, the discrete scheme of the Maxwell’s equations is rewrote with velocity variable added. With the difference scheme in magnetic field remains unchanged, the difference scheme in electric field changed, the novel SFDTD method is used on the moving Plasma Photonic Crystals (PPCs). Also, with the numerical simulation of the moving PPCs by the SFDTD method, this article proves that the transmission coefficients of the PPCs can be changed with the velocity variable added.
