“…It is very important to find out the mechanism and phenomena about the interactions between EM wave and plasma in the study of this technology. In the past twenty years, a number of analytical and numerical methods have been proposed to investigate the wave propagation in plasma [2,3,[12][13][14][15][16][17][18][19][20][21]. Hu et al [15] used a scattering matrix method to calculate the reflection, transmission and absorption characteristic of EM wave propagation in nonuniform magnetized plasma, where the external magnetized field direction is perpendicular to the direction of EM wave propagation.…”

“…Huang et al [18] made a detailed investigation of surface modes at the interface between an isotropic medium and a uniaxial plasma. LaiXuan Mao et al [2,3] did research on the reflection characteristic of EM wave incidence in non-magnetized closed plasma with outer envelope based on the wave impedance matching principle. Their model considered the double-pass attenuation of the rays inside the plasma slab.…”

Abstract-An analytical technique referred to as the propagator matrix method (PMM) is presented to study the problem of electromagnetic (EM) waves interacting with the nonuniform magnetized plasma. In this method, the state vector is proposed to describe the characteristics of eigen waves in anisotropic medium, and state vectors at two different locations are related with each other by the propagator matrix. This method can be used to deal with the phenomenon of the transformation of EM wave polarization induced by anisotropic magnetized plasma, besides the conventional propagation characteristics through plasma slab, which overcomes the drawback of other analytical methods introduced in former studies. The EM problem model considered in this work is a steady-state, two-dimensional, nonuniform magnetized plasma slab with arbitrary magnetic declination angle, which is composed of a number of subslabs. Each subslab has a fixed electron density, and the overall density profile across the whole slab follows any practical distribution function. Based on PMM, a significant feature of strong transformation of EM wave polarization is addressed when an incident wave normally projects on the slab, which leads to the reflected or transmitted waves containing two kinds of waves, i.e., the co-polarized wave and the cross-polarized wave. The effects of varying the plasma parameters on the reflected and transmitted powers of co-polarization and cross-polarization, as well as the absorptive power

“…The angle at which the incident EM wave will strike cylindrical conductor will depend on plasma density, radius of conductor, and radius of plasma envelope. Since density of plasma envelope is function of distance from the center of conductor, it can be modeled as uniform multilayered unmagnetized plasma (Ma et al 2010b). The reflection coefficient of the plasma envelope can be expressed as…”

The concealment of aircraft from radar sources or stealth is achieved either through shaping, or radar absorbing coatings, or engineered materials, or plasma, etc. Plasma-based stealth is a radar cross-section (RCS) reduction technique associated with the reflection and absorption of incident electromagnetic (EM) wave by the plasma layer surrounding the structure. Plasma cloud covering the aircraft may give rise to other signatures such as thermal, acoustic, infrared, or visual. Thus it is a matter of concern that the RCS reduction by plasma enhances its detectability due to other signatures. This needs a careful approach toward the plasma generation and its EM wave interaction. This book presents a comprehensive review of the plasma-based stealth, covering the basics, methods, parametric analysis, and challenges toward the realization of the idea. The book starts with the basics of EM wave interactions with plasma, briefly discusses the methods used to analyze the propagation characteristics of plasma, and its generation. It presents the parametric analysis of propagation behavior of plasma, and the challenges in the implementation of plasma-based stealth technology. This review serves as a starting point for graduate and research students, scientists, and engineers working in the area of low-observables and stealth technology.

This work reports on the effect of plasma area on the frequency characteristics of the monostatic radar cross section (RCS) of a square metallic plate. A dielectric barrier discharge (DBD) plasma actuator consisting of 10 rings is proposed. The actuator is fabricated in three different configurations such that only three inner rings, seven inner rings, and all rings can be biased. By applying an 18-kV bias at 1 kHz, the three types of DBD actuators generate plasma with a total area of 16.96, 36.74, and 53.69 cm 2 , respectively, in a ring or circular form. The experimental results reveal that when the DBD actuator is placed in front of a 20 mm× 20 cm conducting plate, the monostatic RCS is reduced by as much as 18.5 dB in the range of 9.41-11.65 GHz. Furthermore, by generating the plasma and changing the area, the frequency of maximum reduction in the monostatic RCS of the plate can be controlled. The frequency is reduced by nearly 20% in the X band when all rings are biased. Finally, an electromagnetic model of the plasma is obtained by comparing the experimental and full-wave simulated results.Key Words: Dielectric-Barrier-Discharge Plasma, Frequency Tunable, Radar Cross Section Reduction, Surface Area of Plasma.
