Abstract: We report on using the optical mechanical analogy to study the propagation of the electromagnetic wave in
through the plasma layer surrounding the hypersonic object moving in dense gaseous medium. This analogy
allows us to consider plasma sheath surrounding the object as a potential barrier and analyse the process of
electromagnetic wave tunneling. The idea is to embed a dielectric layer as a «resonator» between the surface
of the object and plasma sheath which is supposed to provide an effective tunneling regime. We discuss the
peculiarities of optical mechanical analogy applicability and analyse the radio frequency wave tunnelling
regime in detail. The cases of normal and oblique incidence of radiofrequency waves on the vehicle surface
are studied. The analysis is applied for a problem of overcoming of the communication blackout during the
hypersonic vehicle re-entry into the Earth's atmosphere.
1 INTRODUCTION
Analysis of the tunneling processes for
electromagnetic waves in opaque media regions on
the basis of the well-known optical-mechanical
analogy is used in a huge number of applications.
Typically, these are problems in condensed matter
physics, magnetic hydrodynamics, quantum optics,
physics of photonic crystals and artificial
metamaterials with unique parameters (Shvartsburg,
2007; Narimanov and Kildishev, 2009; Yang et al.,
2012; Bobkov et al., 2016; Jung and Keller, 2017;
Razzaz and Alkanhal, 2017; Li, 2016).
We applied this approach to the solution of the
urgent communication blackout problem (Shi et al.,
2013; Lei et al., 2015; Xie et al., 2016). First, it
allowed us to propose new methods of optimization
of telecommunication systems with an ability of
continuous contact with the hypersonic vehicle. Also
new unobvious limitations on the region of
applicability of optical-mechanical analogy in
problems on the passage of electromagnetic waves
through layers/structures of extremely low
transparency are discussed. Aircraft, rockets, and
missiles moving at supersonic speed in the
atmosphere are covered with plasma sheath
(thickness d is about 0.1–1 meter). Hence we cannot
use for telemetry and control microwaves with
frequencies less than the so-called plasma frequency
(of about 9 GHz for object velocities in the range 8–
15 Mach) and wavelengths comparable or less then
d. We cannot ignore the presence of a plasma sheath
since it is the frequency range from 100 MHz to 10
GHz that is most important for prospective
telecommunication systems (Nazarenko et al., 1994;
Korotkevich et al., 2007; Gillman and Foster, 2009;
Wang et al., 2016; Gao and Jiang, 2015). Plasma
destruction (e.g. by injecting water drops) is also
quite a difficult task.
The most interesting approach is to use the
features of the interaction of ionized gas with
radiation. For overcoming the opaque layer one can
use the nonlinear interaction of three waves in the
plasma layer region: a low-frequency wave carrying
a signal from the Earth, a Langmuir wave and a
high-frequency wave (pump wave) generated from
the onboard source. The reflected (so-called Stokes
wave) carries the information encoded in the signal
to the Earth.
