Abstract-A low frequency (50 Hz) dielectric barrier discharge (DBD) system with a single dielectric cover on copper coil anode is designed to generate and sustain the micro-discharge plasma which is very practical for material processing applications. The DBD system is powered by a high tension ac source consisting of a conventional step up transformer and variac. The dielectric barriers (quartz and glass) between the conducting electrodes appreciably influences the discharge plasma characterized by optical emission spectroscopy technique. Using intensity ratio method, the electron temperature and electron number density are determined from recorded spectra as function of ac input voltage, type and thickness of dielectric barrier and inter-electrode gap. It is observed that both the electron temperature and electron number density increase with the increase in ac input voltage and ε r / d ratio, while a decreasing trend is observed with increase in inter-electrode gap.

“…Over the past few years, a number of finite difference time-domain (FDTD) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] methods have been used to model electromagnetic wave interaction with unmagnetized and magnetized cold plasma. These methods include the recursive convolution (RC) method [2], which becomes piecewise linear recursive convolution(PLRC) method [3] for more precision, the auxiliary differential equation (ADE) methods [4], and current density recursive convolution (JEC) method [5].…”

Abstract-The dispersion relation of piecewise linear recursive convolution finite difference time domain (PLRC-FDTD) method for space-varying plasma is analyzed using a novel equivalent method. The equivalent dispersion and dissipation errors have been taken into account. The efficiency of the novel equivalent method is substantiated by computing the test and reference transmitted electric field. The comparison of the test and reference solutions validates that the equivalent method is an efficient method to analyze the dispersion relation of PLRC-FDTD method used for space-varying plasma.

“…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.
