Book Description
The expressions for the radiated fields of an arbitrary slot on a conducting cylinder coated with a cold plasma sheath with an axial static magnetic field are obtained. It is well-known from the plane wave analysis that the presence of a static magnetic field affects considerably the transmission characteristics of the signal through the plasma sheath. The principal concern of this paper is to consider the effects of a static magnetic field on the radiation of a plasma coated slot antenna. Extensive numerical computations are carried out for the special case of an infinite axial slot. It is found that if the plasma frequency is moderate a small axial static magnetic field could change significantly the radiation patterns of the slotted antenna. Furthermore, the radiation patterns are asymmetric. (Author).
