“…It was experimentally shown in [1] that single sided excitation of a lengthy high frequency (HF) discharge supported by the propagating azimuthally symmetric mode of surface wave (SW) E SW is possible in the gas discharge tubes filled with a rarefied gas. In [2], the authors considered the conditions under which the initial ionization of the gas is conducted at the input to the gas filled discharge tube by the radiation field of the own transmitter at frequency ω and the SW is excited at the plasma-vacuum interface when certain plasma density n cr is reached in the tube, so that (1) where = n e (r) is the density of charges, е and m are the charge and the mass of elec tron, ω is the frequency of the SW field, and r is the distance from the axis of the plasma cylinder.…”

Characteristics of the plasma layer (a plasma antenna of dipole type), excited by the radiation of a transmitter such as the carrier density distribution over the radius of the dielectric tube (near the boundary) and the growth rate of the plasma region along the tube length are considered. It is shown that it is possible to distinguish such typical dimensions as the radius of the dielectric tube, the radius of the plasma column, and the thickness of the skin layer, and, depending on relationships between these dimensions, consider the influ ence of the transition layer on excitation of the surface wave in the plane or cylindrical symmetry.

Several basal theoretical problems for the radiation of plasma antenna are investigated. The system equations are obtained according to the rule of the disturbing current, which is excited by surface waves on the interface between a plasma column and a dielectric tube, and the radiation theory of dielectric antennae. The analysis indicates that there are two kinds of mechanisms to explain the radiation of plasma antennae. The first one is the radiation of the disturbing current, which is similar to the radiation of a metal antenna. In the second case, because the electromagnetic wave partly cannot satisfy the total reflection condition in some specific frequency bands, transmission can be excited in a plasma antenna, which is similar to the radiation of a dielectric antenna. The radiation derived from these two kinds of mechanisms can be superposed in certain frequency bands. In this paper, a radiation directivity function is obtained. The radiation characteristics of plasma antennae are compared with those of metal antennae. The radiation properties of plasma antennae are presented based on numerical calculation. The present results provide an important theory for further investigation in the performance of controlling plasma antennae and plasma antenna arrays.
