The penetration of electromagnetic waves due to their nonlinear interaction into a semi-infinite magnetized plasma (a constant and homogeneous magnetic field is directed perpendiular to the plane plasma boundary) is treated in the kinetic approximation. The case in which the waves are propagating along the normal to the plasma boundary is treated. It is found that two electromagnetic waves, with frequencies ..omega../sub 1/ and ..omega../sub 2/, incident on the plasma excite nonlinear longitudinal waves in the plasma at the sum and difference frequencies, ..omega..=..omega../sub 2/ +- ..omega../sub 1/. A study is made of the case in which the frequencies ..omega../sub 1/ and ..omega../sub 2/ lie in the band corresponding to resonant electron-cyclotron absorption and in which the nonlinear longitudinal waves at the sum and difference frequencies are slightly damped plasma waves and ion--acoustic waves, respectively. The case which is most interesting from the plasma-heating standpoint is that in which nonlinear longitudinal ion--acoustic waves are excited. These waves transfer energy to the plasma ions.
