Abstract

The investigation of the cyclotron maser instability in sources of finite perpendicular extension separated from the denser and cold surrounding plasma by sharp density gradients is made within the waveguide approximation. The general dispersion equation of wave propagation and amplification is obtained and solved numerically for different regimes. It is found that the growth rate of oblique eigenmode increases with the increasing of the perpendicular component of the wave vector directed along cavity boundaries. The structure of electromagnetic fields inside the source region is studied and changes of the wave polarization are discussed.
