Abstract: (1768 Views)
In this paper the propagation of terahertz pulse in a collision cold plasma slab is studied. By using the Maxwell's equations and dielectric constant of a collision cold plasma, the relation for the electric displacement vector and polarization is calculated. Transmission and reflection of terahertz wave in a plasma slab is simulated with one-dimensional Finite Difference Time Domain (FTDT) method and bilinear transform (BT) model. The results show that the characteristics of the plasma slab and the pulse parameters affect the shape and amplitude of the transmission and reflection wave.
