The radio technique for the detection of high-energy cosmic rays consists in measuring the electric field created by the particle showers created inside a medium by the primary cosmic ray. The electric field is then used to infer the properties of the primary particle.
The composition of ultra-high energy cosmic rays is still poorly known and constitutes a very important topic in the field of high-energy astrophysics.
We present a microscopic computation of the radio emission from air showers initiated by ultra-high energy cosmic rays in the atmosphere.
We discuss electric fields generated by cosmic ray air showers at large impact parameters b.
The electric field induced by extensive air showers generated by high energy cosmic rays is considered and, more specifically, its dependence on the shower incident angle.
