Abstract
Characteritics of gyro-synchrotron emission from energetic electrons are considered. Radiation waves consist of two circularly polarized waves, right-and left-handed. when the pitch angle of an electron is smaller than π/2, most radiated power of right-handed wave concentrates in the narrow cone which is formed by the pitch angle arownd the magnetic line of force. This power is much greater than that of left-handed wave.
The polarization of composite waves is determined by adding right-and left-handed waved, and is only determined, by the pitch angle (ψ) and the ratio of the electron speed to the light speed (β).
