Abstract:
The skin depth has been calculated using the surface impedance for the transverse waves
in bi-kappa distributed plasma. The effects of temperature anisotropy on the surface
impedance and the skin depth have been studied using the kinetic model for an
electromagnetic wave striking on a plasma surface. It is noted that the real part of the
surface impedance has direct relation with temperature anisotropy and kappa parameter,
while changes inversely with the wave frequency. On the other hand the imaginary part,
however, is not affected by kappa parameter and temperature anisotropy significantly but
changes directly with the frequency. It also been calculated that the skin depth is inversely
related to the frequency in both resonant and non-resonant case. It has been found that
in low frequency regime (resonant case) the skin depth first increases with increasing
temperature anisotropy and then remains constant, while in high frequency regime (non -resonant) the skin depth increases linearly by increasing the temperature anisotropy. It
has been calculated that the skin depth in both high and low frequency regime increases
by increasing the kappa parameter. The comparison between the skin depth at high and
low frequency shows that skin depth is greater in low frequency regime/resonant case.
