A Macroscopic Description of Coherent Geo-Magnetic Radiation from Cosmic Ray Air Showers

Abstract

We have developed a macroscopic description of coherent electro-magnetic radiation from air showers initiated by ultra-high energy cosmic rays due to the presence of the geo-magnetic field. This description offers a simple and direct insight in the relation between the properties of the air shower and the time-structure of the radio pulse.Comment: 10 pages, 8 figures; submitted to Astroparticle Physic
