The problem of non-linear electromagnetic scattering from complex structures is here addressed. Non-linear scattering is critical in satellite environment, where many powerful transmitters are closely packed with many high sensitivity receivers since the passive intermodulation components due to the transmitters can interfere with the receivers.

Abstract
The problem of non-linear electromagnetic scattering from complex structures is here addressed. Non-linear scattering is critical in satellite environment, where many powerful transmitters are closely packed with many high sensitivity receivers since the passive intermodulation components due to the transmitters can interfere with the receivers. In this paper a heuristic approach, useful to determine the power level of the passive intermodulation fields scattered by uniform planar surfaces, having a non-linear behaviour, excited by an electromagnetic wave having a specific power density is presented.
