Abstract- In this paper the propagation of terahertz pulse in a hot unmagnetized plasma slab is studied. In interaction of the electromagnetic waves, the plasma acts as a dielectric medium. Transmission, reflection and absorption of terahertz wave in a plasma slab is simulated with one-dimensional Finite Difference Time Domain method and using the plasma dielectric constant established based on a hot plasma dispersion relation. The problem is investigated by considering the sheath and space-varying parameters of bounded plasma. The results show that the different electron density profiles affect on shape and amplitude of the reflected wave.
Keywords: FDTD method, bounded hot unmagnetized plasma, terahertz waves.
