Abstract
The reflection and transmission of electromagnetic waves by a moving dispersive dielectric half-space or slab are investigated theoretically. The dispersive dielectric medium is assumed to be a cold plasma medium. Two cases of the movement are considered: (a) The plasma medium moves parallel to the interface. (b) The plasma medium moves perpendicular to the interface. It is interesting to note that, for case (a), the reflected and transmitted fields for an incident plane E wave are independent to the movement of the plasma medium. For case (b), the reflected wave and the transmitted wave are functions of the velocity of the moving plasma medium. Detailed results on the reflection and transmission coefficients for case (b) are given and discussed. In the present analysis, the electric vector of the incident wave is assumed to be polarized in a direction that is normal to the plane of incidence.
