“…A diagram of the experimental setup is shown in Figure 1. It includes a plasma generating device (3), receiving and transmitting horn antennas (11,12) and the Keysight Vector Network Analyzer (1), which was used to measure electromagnetic waves attenuation after the wave passes through the plasma. The experimental setup was enclosed with an absorbent sponge (2) to remove interference from the surrounding environment.…”

This paper presents a new composite grid electrode structure for the generation of plasma that is suitable for modeling microwave radiation transmission through atmospheric plasma. The new grid anode-composite cathode (GA-CC) structure is to be contrasted with the ordinary grid anode-cathode plate (GA-CP) structure. It is found that the breakdown voltage of the new GA-CC electrode structure is lower than that of the GA-CP structure and is a bit shifted to the right on the Pd-axis. An advantage of the GA-CC structure over the GA-CP structure is that it requires a lower voltage to generate the same current. It is found that plasma generated by the new GA-CC structure selectively strengthens electromagnetic waves attenuation in the frequency range of 9-12 GHz.

“…A communication channel through the plasma sheath can solve the blackout problem for re-entry of spacecrafts [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. The essence of this problem is that a supersonic flying vehicle in the atmosphere is inevitably covered by a weakly conducting ionized gas, which is opaque for electromagnetic waves in the frequency range 100 MHz–10 GHz (the most important range for current telecommunications).…”

We consider two of the most relevant problems that arise when modeling the properties of a tunnel radio communication channel through a plasma layer. First, we studied the case of the oblique incidence of electromagnetic waves on a layer of ionized gas for two wave polarizations. The resonator parameters that provide signal reception at a wide solid angle were found. We also took into account the unavoidable presence of a protective layer between the plasma and the resonator, as well as the conducting elements of the antenna system in the dielectric itself. This provides the first complete simulation for a tunnel communication channel. Noise immunity and communication range studies were conducted for a prospective spacecraft radio line.

“…The basic reason of this phenomenon is that several factors affect the propagation of electromagnetic waves in the plasma sheath, such as the physical characteristics of the plasma sheath itself, the radar antenna, and the flight attitude of the vehicle. The first two factors have been investigated at length [3]- [6]. Besides, the National Aeronautics and Space Administration conducted several experiments and performed extensive research to resolve this ''communications blackout'', including the Radio Attenuation Measurements Program, the Hyper-X Program and the Hypersonic Technology Vehicle (HTV) Program [7]- [10].…”

Hypersonic velocities can theoretically affect the propagation of electromagnetic waves in a plasma sheath covering a vehicle. This article is the continuation of our previous study and, for the first time, investigates the reflection characteristics of electromagnetic waves by a moving bounded plasma slab and examines five typical plasma parameters in detail when the plasma moves parallel to the interface. The results show that the motion of the plasma slab significantly affects electromagnetic propagation, and the reflection coefficient oscillates with the velocity of the plasma sheath. In addition, different physical parameters cause different oscillation characteristics. Various interesting features of the reflection coefficient are obtained, which are very important for researching the propagation of electromagnetic waves in this extreme physical environment or providing reference for researching ''blackouts'' in the future. INDEX TERMS Electromagnetic waves, moving nonuniform bounded plasma, reflection coefficient.
