n this paper, new theoretical findings on the application of magnetic field in effective transmission
of electromagnetic (EM) waves through a plasma sheath around a hypersonic vehicle are reported.
The results are obtained by assuming the plasma sheath to consist of nonextensive electrons and
thermal ions. The expressions for the electric field and effective collision frequency are derived
analytically in the framework of nonextensive statistics. Examination of the reflection, transmission,
and absorption coefficients regarding the strength of the ambient magnetic field shows the
significance of q-nonextensive parameter effect on these entities. For small values of the magnetic
field, the transmission coefficient increases to unity only in the range of 1 < q < 1. It is also found
that the EM wave transmission through the nonextensive plasma sheath can take place using lower
magnetic field strengths in the presence of superthermal electrons compared with that of Maxwellian
ones. It is observed that superthermal electrons, with nonextensive parameter, q < 1, play a dominant
role in overcoming the radio blackout for hypersonic flights.
