Abstract
Electromagnetic modes (ordinary and extraordinary) for strongly magnetized plasma are studied and their damping factors γor and γex 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.
