Microwave emission of solar flares

The theory of gyroresonance emission of relativistic nonthermal particles in a magnetoactive plasma is discussed. A model of a microwave burst of radio emission is created which allows for self-absorption and the influence of the thermal plasma of the solar atmosphere. The model is compared with experimental material, demonstrating the effectiveness of the approximations used. An estimate is obtained for the magnitude of the magnetic field in the region of a source of a microwave burst.
