Induced amplification of extraordinary-mode electromagnetic waves in a magnetized plasma is investigated. The analysis is performed for a plasma which consists of two components: a relatively dense species of thermal plasma and a diffuse population of suprathermal electrons characterized by a loss cone-type distribution. The excitation mechanism is primarily due to the interaction of the electromagnetic waves with the energetic electrons via the relativistic cyclotron resonance which arises because of the momentum dependence of the gyrofrequency. The present study is particularly concerned with waves propagating perpendicularly and nearly perpendicularly with respect to the external magnetic field, since it is expected that for these cases the cyclotron damping due to thermal electrons is vanishingly small and the growth rates are maximum. The results indicate that excitation occurs primarily for frequencies near the first two gyroharmonics.
