Application of MW-FDTD to simulate EM wave propagation in plasma for long distance

To reduce the computational burden of normal finite-difference time-domain (FDTD) method, moving window technique was used here to predict the electromagnetic wave propagation in plasma slab. The stretched coordinate perfectly matched layer (SC-PML) with complex frequency shifted (CFS) equations was applied to absorb the backward reflection. This technique can save considerable computation resources for long propagation distance, and the high accuracy of MW-FDTD method is confirmed by compare these results to the analytical solution and full model FDTD method results.
