Abstract :
The radiation characteristics of an infinitesimal slot situated on an infinite perfectly conducting ground plane and covered by an anisotropic plasma layer are investigated, for the case of the magnetostatic field parallel to the ground plane but perpendicular to the slot. The radiation conductance of the slot contributed by the space waves and the power pattern are evaluated, and their dependence on the thickness of the plasma sheath, the signal frequency, the strength of the magnetostatic field and the effective collision frequency is examined. It is found that a suitable application of a static magnetic field increases the radiation conductance and the power pattern, for practically all directions, and these improvements are obtained even though the static magnetic field is not strong enough to render the plasma transparent for any direction of propagation.
