Electromagnetic Weibel instability in spatial anisotropic electron–ion plasmas

The Weibel instability due to temperature anisotropy of electrons and ions in a plasma the presence cold warm is reported. Numerical calculations normalized growth rate are carried out when frequency electromagnetic waves greater than or less thermal velocity for typical existing parameters. increases with an increasing wave number, after attaining maxima, it decreases effects. Therefore, parabolic plot obtained rate. threshold values depend on On value ratio either component, observed increases. There considerable contrasting effect plasma. addition stabilizes reduces maximum values, while decrease domain instability. Our theoretical investigations good agreement experimental results.
