Photon Damping in a Strongly Magnetized Plasma

The process of electromagnetic wave propagation in a strongly magnetized (magnetic fields exceeding 4.41 ×10^13 G) charge-symmetric plasma is investigated. Taking the change in the dispersion properties of a photon in a magnetic field and plasma into account, it is found that, as in the case of a pure magnetic field, the process of photon damping in a magnetized plasma has a nonexponential character. It is shown that the effective photon absorption width is significantly smaller in comparison with the results in the literature.
