FDTD Solution for Signal Transmission in Plasma Sheath

An inhomogeneous ionized plasma layer is generated around the hypersonic vehicle, which may cause radio blackout. In this paper, an innovative multi-physical method combining plasma fluid equations and Maxwell's equations is proposed. Numerical results indicate that the electron concentration can be significantly reduced via the applied magnetic field to create a magnetic window. In addition, this paper proposes a set of simulation methods to realize the process of receiving signals from hypersonic vehicle, avoiding complicated and expensive flight experiments. Providing theoretical basis and simulation data for solving the problem of radio blackout in engineering. This is also one of the innovations of this article, therefore, our research has an extensive application prospect.
