Two kinds of plasma monopole antennas are simulated and analyzed in this paper. For different radius, reflection coefficient, radiation pattern and radiation efficiency of a cylindrical plasma monopole antenna are calculated respectively. According to actual situation, a conical plasma monopole antenna with different cone angle is simulated. Impedance and radiation characteristics of the plasma antenna are similar to the metal monopole antenna.

“…Recently, there has been a growing interest in the use of plasma discharges [3][4][5][6][7] as passive or active antenna elements because the latter have potential advantages over conventional metallic antennas. Most notably, plasma discharges can be employed to build reconfigurable structures with low radar cross section.…”

“…In fact, it has been shown that the performance of a GPA is equivalent to that of a metallic counterpart in every respect [12]. However, GPAs have received attention and stimulated research for some distinctive characteristics of theirs such as being transparent to incoming EM waves whose frequency is greater than the plasma frequency [5] as well as the possibility to be reconfigured electrically -rather than mechanically -with respect to frequency, gain and beam-width. Reconfiguration capabilities stem from the accurate control of the plasma density and, if present, an applied magneto-static field B 0 [13][14][15].…”

Abstract-We present the numerical parametric study of a reconfigurable plasma antenna array (PAA) composed of a metallic half-wavelength dipole and a set of cylindrical plasma discharges arranged in a planar square lattice. Our results, obtained with the linear embedding via Green's operators (LEGO) method, indicate that beam-forming and beam-steering functionality can be achieved and controlled by appropriately choosing the number and position of the active plasma discharges around the dipole. Furthermore, we show that an external static magnetic field and the plasma density have a noticeable effect on the radiation pattern of the antenna.

“…Plasma technology is a kind of technology with novel concept and newly working principle, and its latent application in electromagnetic (EM) field is splendid, such as plasma stealth technology [1][2][3], plasma antennas [4][5][6], plasma diagnostic [7,8], plasma photonic crystals [9] and communications through plasma sheath [10][11][12][13][14]. 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.…”

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
