Including Directivity in Reverberation Chamber Radiated Susceptibility Testing

Abstract

The susceptibility of electronic equipment against electromagnetic irradiation depends on irradiation direction and polarisation. We show how this dependency can be taken into account when performing a radiated susceptibility test in the reverberation chamber. In the reverberation chamber the stress onto the equipment under test increases with the number of independent stirrer positions in the same manner as, in open space the stress onto the equipment under test increases with the number of independent irradiation directions and polarisations.
