| Abstract: | Collisionless absorption of linearly polarized electromagnetic wave in a plasma with anisotropic bi-Maxwellian electron velocity
distribution is investigated. Due to the wave magnetic field influence on the electron kinetics in the skin layer, the wave
absorption is found to significantly depend on the degree of the electron temperature anisotropy. Depending on the value of
the skin layer anomaly parameter, and on the electron temperature anisotropy degree, the conditions are found when a significant
decrease or increase of the collisionless absorption is expected.
