Abstract
The index of refraction and the electron cyclotron absorption coefficient at ω≊ωc in the Doppler regime are examined for a plasma in thermal equilibrium. Regimes where the known analytical approximations fail are quantitatively delineated. The exact numerical solution to the dispersion relation is given in the regimes where known analytical theory fails.Keywords
