“…Recently, more and more studies have been conducted in this area. THz wave propagation performance in discharged plasma was studied in [7] by Tosun et al in 2009. The frequency of 200 GHz was assigned to the next intersatellite communication band by the International Telecommunication Union (ITU) [8].…”

Radio communication is a vital challenge during vehicle reentry into the Earth’s atmosphere in practice, because the plasma covering the aerospace vehicle can block the communication as the spacecraft reenters the atmosphere. To investigate the potential of the terahertz wave, the transfer function method is first applied to study the wave propagation behavior in plasma, validated by the numerical and the experimental results. The comparison of all three results shows a decent agreement, with the average absolute difference around 1.1 dB for the power loss between the theoretical and numerical results for 100 GHz and 220 GHz and around 0.8 dB for the power loss between the simulation and measurement for 100 GHz and 220 GHz, which shows the validity of the transfer function method and the great potential of the numerical model for future study. Moreover, the results shows the possibility of the application of the THz wave to deal with the blackout problem.

“…[12] As the basis of communication between the hypersonic vehicles and the ground control center, the interaction between plasma and THz wave (absorption, reflection, and transmission) is a key issue to be analyzed. Over the past few years, the propagation characteristics of the THz wave in plasma have been investigated by different methodologies, such as the analytical method, [13][14][15][16][17] experimental method, [18] scattering matrix method (SMM), [19,20] propagation matrix method (PMM), [21] finite-difference time-domain (FDTD) method, [22][23][24][25][26][27][28] Wentzel-Kramer-Brillouin (WKB) method, [29,30] and so on.…”

The propagation characteristics of oblique incidence terahertz (THz) waves through non-uniform plasma are investigated by the shift-operator finite-difference time-domain (SO-FDTD) method combined with the phase matching condition. The electron density distribution of the non-uniform plasma is assumed to be in a Gaussian profile. Validation of the present method is performed by comparing the results with those obtained by an analytical method for a homogeneous plasma slab. Then the effects of parameters of THz wave and plasma layer on the propagation properties are analyzed. It is found that the transmission coefficients greatly depend on the incident angle as well as on the thickness of the plasma, while the polarization of the incident wave has little influence on the propagation process in the range of frequency considered in this paper. The results confirm that the THz wave can pass through the plasma sheath effectively under certain conditions, which makes it a potential candidate to overcome the ionization blackout problem.
