Perpendicularly propagating electromagnetic modes in a strongly magnetized hot plasma with non-Maxwellian distribution function

Abstract

Electromagnetic modes ordinary and extraordinary for strongly magnetized plasma are studied and their damping factors or and ex are calculated using non-Maxwellian velocity distribution function. It is observed that for moderate values of the spectral indices r and q used in r, q distribution functions , both the damping decrements show substantial change. As the value of the spectral index r increases for a fixed value of q, the damping increases for the O mode but decreases for the X mode. In the limiting case of r=0, q→ , the damping factors reduce to the standard Maxwellian values. © 2006 American Institute of Physics
