On the Spectrum of Geomagnetic Radio Emission from Extensive Air Showers in a Kinetic Model

Geomagnetic radio emission from an extensive atmospheric shower (EAS) is calculated in a kinetic model where, in contrast to previous models, the radiation of each electron and positron of the shower disk is calculated taking into account their spatial distribution in the disk, the disk evolution along the EAS track, energy spectrum and multiple scattering. Radio emission spectra are found at distances of 100 and 800 m from the vertical EAS axis in the frequency range of 40 to 340 MHz with a resolution of 20 MHz.
