Radiation from long conducting tethers moving in the nearearth environment
Abstract
The radiation properties of a long metallic tether moving in the ionospheric plasma are considered. The physics of the emission of radiation from a moving tether, the natural current of which is or is not pulsated, is discussed. The formalism for an infinitely long moving current source is developed and the basic formulae for radiation resistance are given. Approximate analytical expressions and numerical results are presented for the radiation of different plasma modes, both in the hydromagnetic and in the whistler ranges. The results obtained are summarized and used, for typical ionospheric parameters, to estimate total radiation resistances for various modes for both a moving tether and a tether operated as an antenna at a given frequency.
