Resumen:
Abstract. Over the last decades, radio detection of air showers has been established as a detection technique for ultra-high-energy cosmic-rays impinging on the Earth´s atmosphere with energies far beyond LHC energies. Todays second-generation of digital radio-detection experiments, as e.g. AERA or LOFAR,are becoming competitive in comparison to already standard techniques e.g. uorescence light detection. Thanks to a detailed understanding of the physics of the radio emission in extensive air showers, simulations of the radio signal are already successfully tested and applied in the reconstruction of cosmic rays. However the limits of the computational power resources are easily reached when it comes to computing electric elds at the numerous positions requested by large or dense antenna arrays. In the case of mountainous areas as e.g. for the GRAND array, where 3D shower simulations are necessary, the problem arises with evenstronger acuity. Therefore we developed a full parametrisation of the emitted radio signal on the basis of generic shower simulations which will reduce the simulation time by orders of magnitudes. In this work we will present this concept after a short introduction to the concept of the radio detection of air-shower induced by cosmic rays.
