The principle of interaction of charge carrier currents with microwave fields is based on the work of modern generators and microwave amplifiers. In such devices, control is carried out with the help of elements of waveguide paths: resonators and remote-control systems. All microwave devices can be divided into two categories: vacuum and solid-state. The first is the magnetron. In which between the cathode and the anode due to an external source of constant voltage arise crossed static electric and magnetic fields. The frequency of microwave oscillations and the geometric dimensions of the resonators are closely related to each other. It is obvious that the generation frequency depends on the intensity of the magnetic field. Rotating in circular orbits, electrons repeatedly give their energy to the microwave field, so that the KKDgen is 90%. The waveguide constructed by us can be regarded as a system of plane mirrors forming a closed cavity. At the same time on one of the walls of the waveguide there is a whip radiator-antenna. The shape of the generating wave is quite complex and similar to the dipole radiation field in the near zone, but it can be considered as the sum of plane waves propagating in different directions except for the direction along the axis of the radiator. Since microwave currents propagate along the surface of the conductor, the inner surface of the waveguide must be perfectly smooth, without scratches, craters and outgrowths. Defects of the surface of the waveguide - is a serious obstacle to microwave currents.
