Modeling and analysis for dynamical Doppler shifts on terahertz communication signals propagating in inhomogeneous hypersonic plasma sheath

Xiangmeng Lin, Junyi Zhang, Kai Yuan, Ziyang Zhao et al. • AIP Advances (2025)

Previous studies have shown that terahertz (THz) signals could penetrate hypersonic plasma sheaths. Thus, it is considered to be a potential solution to the “blackout” problem. Nevertheless, although previous studies have systematically rev...
