Abstract
When two monochromatic electromagnetic (em) waves mix in a uniform magnetized plasma, a longitudinal wave is excited in the plasma. We derive an expression for the energy absorbed by the ions in the case the frequency difference of those two em waves is tuned to the ion cyclotron frequency. For time much longer than the period gyration of an ion, it is shown that mixing geometries producing small values of the wave number of the excited electrostatic wave are more effective in heating up the plasma.
