摘要
We consider the process of the nonlinear absorption of Alfven waves in inhomogeneous incompressible dissipative plasma. It is shown that taking into account certain types of radiation, in particular, the bremsstrahlung and the photorecombination radiation, leads to a finite penetration depth of an Alfven wave and a steady quasistationary absorption regime. The effect of taking into account the synchrotron radiation is insignificant. Density inhomogeneities have a Gaussian distribution with a parameter corresponding to a hump or a hollow. Dependences of the maximum values of the temperatures of electrons and ions on the value of the hump and the depth of penetration of the Alfven wave are obtained.
