A novel finite-difference time-domain (FDTD) method, called shift operator FDTD(SO-FDTD) is developed for dispersive media plasma. The recursive relation among operators is used. The dielectric property of dispersive media is written as rational polynomial function. In this paper, with approximate different temperature, reflectance of electromagnetic wave is calculated by using SO-FDTD method. The effect of temperature change on the reflectance is discussed. The study illustrates that higher temperature helps plasma to absorb electromagnetic wave.

“…Since 1990s, academic institutions and researchers, overseas and domestic, have been studying plasma stealth technology [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The concept of plasma stealth was proposed first by Vidmar [1], who theoretically studied the reflection, transmission and absorption characteristic of EMW propagation in un-magnetized plasma.…”

Abstract-Stealth characteristic of two dimensional cylinder plasma envelopes is studied. Three cases about plasma refraction effect, reflection characteristic and attenuation by absorbing electromagnetic wave (EMW) are concerned synthetically. As for plasma refraction stealth, EMW traces equation in cylinder plasma is deduced; a novel concept of plasma refraction deviation angle is presented; the relation between refraction deviation angle and incidence angle of EMW is yielded; the relation between refraction deviation angle and plasma density distribution is made out. As for reflection stealth and attenuation stealth, reflection calculation of multi-layer plasma is presented first, and plasma collision frequency as well as corresponding collision absorption is taken into account simultaneously, then EMW reflectivity with double-path attenuation is obtained. It is shown that cylinder plasma envelopes considering the three cases above could make distinct stealth.Corresponding author: L.-X. Ma (mars982133@163.com). 84Ma et al.

“…Laroussi and Roth [13] derived the relationship of electron density, collision frequency, and incident angle with absorbed power and reflected power in unmagnetized plasma using the WKB method. Petrin [14,15] analyzed the nonlinear mechanism between EM waves and plasma by studying the left-hand polarized wave and right-hand polarized wave, respectively. Kim and Boyd [16] got the attenuation and reflection of reentry signals in different electron densities and collision frequencies.…”

Abstract-Fluctuations of the reentry plasma sheath can affect the propagation of Electromagnetic waves. The relations between fluctuations and the propagation of electromagnetic waves are analyzed. The effects on polarization properties in L-band, S-band and Ka-band during a typical reentry process are studied using methods derived by synthesizing the compressible turbulent flow theory, plasma theory, and electromagnetic wave theory together. Results show that in L-band and S-band, the effects increase with the altitude, while in Ka-band, the effects decrease with altitude. The effects at high altitude above 60 km are prominent in L-band and S-band, while the effects at middle and low altitude below 60 km in Ka-band are obvious. The effects in L-band and S-band are much bigger than that in Ka-band and can affect the signal properties of TT&C systems significantly, while the effects in Ka-band are much milder. The waves with large oblique incident angle can encounter much more severe conditions than that with small angle.
