State of the art in the Jovian radio arc modelization

The Jovian radio arcs are decameter emissions related to the Io-Jupiter interaction. Their arc shape in the time frequency plane is known to be due to geometrical visibility effect on sources spread along an "active" magnetic field line. The state of the art in their modelization will be presented, including some recent results which permit to deduce from their shape the position of the active field line relative to the Io field line and the emitting particle energy. This modeling is permitted by a numerical code, which was also used to model the Cassini observation of Saturn. The interest on such a modelization of the future observations of JUNO will be discussed.
