Analysis of the reflection of electromagnetic waves in an unsteady moving magnetized plasma slab

The reflection index of an unsteady moving magnetized plasma slab irradiated by an electromagnetic wave is investigated. The direction of the external magnetic field is parallel to the plasma surface and the electromagnetic wave is normally incident on a gas slab and produces the plasma. This gas slab is being ionized by another source and the density of the mentioned unsteady plasma increases with time. The effects of the density growth rate, velocity, thickness of the plasma slab, and the external magnetic field on the reflection index are simulated.
