The gyro-synchrotron radiation from an electron spiraling in a magnetoplasma and the influence of the ambient plasma on it are considered. It is pointed out that this influence is more important for the extraordinary mode (X-mode) than the ordinary mode (O-mode). The appearance of the anomalous X-mode with a narrow band and great radiation power can be expected.
Using the Lienard-Wiechert potentials, the electromagnetic fields by an accelerated electron are deduced. It is assumed in this paper that the ambient plasma which is homogeneous, cold, collisionless is immersed in a constant magnetic field, and the presence of ions may be neglected.
The results we have obtained are useful for the interpretation of some characteristics of the electromagnetic fields by a charged particle spiraling in the magnetic field of the Sun, the Jupiter and in the geomagnetic field.
