Energy Distribution Along the Focal Axis of a Metallic Cylindrical Parabolic Reflector Covered With a Plasma Layer

The deviation of the energy distribution along the focal axis of a long metallic cylindrical parabolic reflector, which on its surface contains a uniform cold collisionless plasma, is investigated. In addition, the effects of some physical parameters such as the plasma and wave frequencies and the thickness of plasma layer on this energy distribution and the reflected and the transmitted electromagnetic fields are studied. It is shown that the maximum value of the reflected intensity increases by increasing the incident wave frequency and by decreasing the plasma layer thickness and the plasma frequency.
