“…Mechanisms such as aerodynamic shape modification [6], electrophilic fluid injection, surface catalysis effects [7] and E×B drift [8][9][10] mitigate the plasma sheath by reducing the electron plasma density. While other mechanisms keep the plasma sheath invariant, for example, wave frequency modification [11], laser communication [12], magnetic windows [13], resonant transmission [14], electron acoustic wave transmission [15] and three-wave interactions [16] comply with the plasma sheath and mitigate blackout by exploring and utilizing the EMW propagation characteristics in the plasma. However, EMW energy dissipation caused by the plasma sheath has not been focused on and the power deposition within the plasma sheath is ambiguous.…”

Energy dissipation and power deposition of electromagnetic waves (EMW) in the reentry plasma sheath provide an opportunity to investigate ‘communication blackout’ phenomena. Based on a finite element method (FEM) simulation, we analyze variation of EMW energy dissipation and power deposition profiles dependent on the wave polarization, wave incident angle, plasma density profile and electron collision frequency. Cutoff and resonance of EMW in the plasma sheath are crucial in explaining the regulation of energy dissipation and power deposition.

Rapid progress in exploiting X-ray science has fueled its potential application in communication networks as a carrier wave for transmitting information through a plasma sheath during spacecraft reentry into earth's atmosphere. In this study, we addressed the physical transmission process of X-rays in the reentry plasma sheath and near-earth space theoretically. The interactions between the X-rays and reentry plasma sheath were investigated through the theoretical Wentzel–Kramers–Brillouin method, and the Monte Carlo simulation was employed to explore the transmission properties of X-rays in the near-earth space. The simulation results indicated that X-ray transmission was not influenced by the reentry plasma sheath compared with regular RF signals, and adopting various X-ray energies according to different spacecraft reentry altitudes is imperative when using X-ray uplink communication especially in the near-earth space. Additionally, the performance of the X-ray communication system was evaluated by applying the additive white Gaussian noise, Rayleigh fading channel, and plasma sheath channel. The Doppler shift, as a result of spacecraft velocity changes, was also calculated through the Matlab Simulink simulation, and various plasma sheath environments have no significant influence on X-ray communication owing to its exceedingly high carrier frequency.
