This article describes a magneto-optical study of the faraday effect in rare-earth ferrite garnets. The Faraday effect is an odd magneto-optical effect in terms of magnetization, that is, the sign of the Faraday rotation depends on whether the direction of the light propagating in the crystal coincides with the direction of the magnetization vector M, or is antiparallel to the vector M. This circumstance underlies the well-known method of visual observation of magnetic domains in rare-earth ferrites - grenades.

In article considered satellite communication work and frequency aspects. And their meaning in telecommunications, radio, and television, internet deliver.

In the continue stated about base elements of the system and their principia’s. Stopped on  frequency kinds and transmissions. How it can be sent and received.

Talked about frequency, which it is sent by the transponder is downlink frequency. Shoved some pictures of the system. Talked about advantages ind disadvantages of the exploitations. And sphere of use of SCS (Satellite Communications). Given and analyzed comparative tables of the SCS. Analyzed propagation of wave near the Earth’s surface, what are referred to as ground waves are often separated into space waves and surface waves. Given several mathematical expressions.
