Reflection, transmission and absorption coefficients of a dusty plasma slab

The reflection, transmission, and absorption coefficients of a dusty plasma slab at terahertz frequency are simulated using the shift operator finite-difference time-domain (SO-FDTD) method. The problem which incorporates both frequency dispersion and dust particles' contribution is solved for the electromagnetic waves propagation in dusty plasmas. The numerical verification of the approach is performed by comparing with the numerical results in reference. The computed results show that terahertz waves may have the potential application in the plasma diagnostics and blackout communication.
