TLDR
In this article, it is predicted that for a given operating frequency, there exist certain plasma densities for which the system is resonant, and this very strongly enhanced radiation is fully confirmed by experiments.Abstract:
The plasma sheath existing between an antenna ana a surrounding plasma layer plays an essential role. It is predicted that, for a given operating frequency, there exist certain plasma densities for which the system is resonant, and this very strongly enhanced radiation is fully confirmed by experiments.read more

Improved radiation from a spherical antenna by overdose plasma coating
C. Lin,Kun-Mu Chen +1 more
TL;DR: In this paper, it was shown that the radiation from a plasma-coated spherical antenna can be enhanced if the antenna is operated at a frequency much lower than the plasma frequency, and if the dimensions of the antenna and the plasma layer are appropriately chosen.

A matching approach to communicate through the plasma sheath surrounding a hypersonic vehicle
Xiaotian Gao,Binhao Jiang +1 more
TL;DR: In this article, a matching approach has been proposed for the first time in order to overcome the communication blackout problem suffered by hypersonic vehicles, which utilizes a double-positive (DPS) material layer surrounding a HV antenna to match with the plasma sheath enclosing the vehicle.

On collisionless energy absorption in plasmas: Theory and experiment in spherical geometry
TL;DR: In this paper, Walker et al. investigated the rf impedance characteristics of a small spherical probe immersed in a laboratory plasma and found that the impedance becomes resistive even though the plasma is effectively collisionless, at frequencies below the bulk plasma frequency, thus leading to collisionless energy absorption.

Enhanced radiation from a plasma-imbedded antenna
K.M. Chen,C.C. Lin +1 more
TL;DR: In this article, the radiation of a monopole antenna imbedded in a finite volume of plasma can be enhanced if the antenna is operated at a frequency much lower than the plasma frequency and the antenna dimensions are properly chosen.

Radiation from a spherical antenna covered by a layer of lossy hot plasma. Theory and experiment
C.C. Lin,Kun-Mun Chen +1 more
TL;DR: In this article, a spherical antenna is covered by a finite layer of lossy hot plasma and the radiation of this antenna is quite different from that of the same antenna imbedded in an infinite plasma.
