“…In this section, the damping rates of the classical and acoustic-laden twisted ion wave are quantified for specific parameter choices and plotted versus kλ D+ (the normalized Debye length of positive ions) in bi-ion plasma containing non-thermal Kappa distributed positive and negative ions 12 . In Figures 1 to 10, we study the dependency of the normalized Landau damping rate γ/ω r on various parameters.…”

Waves in bi-ion plasmas are affected by asymmetry.The kinetic theory of the Maxwellian and Lorentzian/Kappa-distributed bi-ion plasma is ameliorated to incorporate the transfer of orbital angular momentum from the helical electric field to the plasma modes. By operating the Laguerre-Gaussian (LG) function, the perturbed distribution function and helical electric field are decomposed into characteristic axial and azimuthal components. In symmetric bi-ion plasmas, the conventional ion modes/waves are only present if both ions have similar masses and the concentration of the electrons is negligible. An imbalance of the symmetry is considered by the contamination of a small fraction of the heavy immobile ions, which urges the negative ions to become heavier than the positive ions in the bi-ion plasma system. The distinct masses of the positive and negative ions provoke mass-asymmetry in the Kappa-distributed bi-ion plasmas. The signature of the unique acoustic-laden twisted modes in non-Maxwellian asymmetric bi-ion plasma is perceived by the temperature of the lighter positive ions and the dynamics of the heavier negative ion. The deliberated results of Landau damping are displayed for distinct values of the azimuthal wave-number and spectral index, temperature-variation and mass-asymmetry.

This paper theoretically and experimentally studies the radar reflection signal characteristics in a multi-domain using a closed plasma generator, especially for a correlation domain. A multi-domain computation method is proposed for a radar signal reflected by a metal covered with plasma. The reflected signal characteristics are studied in the time, frequency, and correlation domain. A closed plasma generator device is designed to verify the computation method for the radar signal reflected from metal plate covered with plasma experimentally. The plasma in the device is terminated by a transmission window at one end and a metal plate at another end, which is able to provide the environment for a radar signal reflection experiment. Based on the theoretical and the experimental results, the time and frequency domain of radar reflection signal not only show the amplitude attenuation characteristics but also frequency dispersion phenomenon. For the correlation domain characteristics of the radar reflection signal, the peak value in correlation domain significantly decreases, which demonstrates the stealth effect of the plasma. The effect of plasma and radar parameters on the peak value decrease phenomenon, as well as the stealth effect in the correlation domain, is further analyzed.
