The origin of ultrahigh-energy cosmic rays (UHECRs)(E $\ge$ 10$^{17}$ eV) is a fundamental question of astroparticle physics. The induced shower of secondary particles in the atmosphere of the Earth provides essential information on the cosmic ray itself: arrival direction, primary energy, and mass. In the air shower many electrons and positrons form a pancake-shaped particle front with a typical thickness less than 1 m close to the shower axis to more than 10 m far from the shower axis The geomagnetic field induces a drift velocity in these particles which is perpendicular to the direction of the initial cosmic ray. The generated current is a source of coherent emission of electromagnetic waves at wavelengths larger than the size of the dimension of the charge cloud i.e., for radio frequencies in the range of 30-300 MHz.
