Show Abstract
The cyclotron maser instability is a well-known radiation emission mechanism responsible for radio emissions in magnetized planets and for laboratory microwave generation devices. The present paper discusses mechanisms and properties of cyclotron maser instability driven by a ring-beam distribution of energetic electrons with application to the quasiperpendicular collisionless shock. It is shown that the fast extraordinary and ordinary electromagnetic waves as well as slow upper-hybrid Z-mode are excited over a wide range of physical parameters. The implications of the present findings for actual applications including the coronal type II radio source are also discussed.
