Full-wave Validation of Plane Waves Model for Numerical Dosimetry in Reverberation Chambers

A full wave method developed for the analysis of lossy dielectric disks is applied to the evaluation of the field induced in a Petri dish exposed in a reverberation chamber. The rich scattering environment can be modeled by means of a plane wave expansion, which is usually approximated taking into account only a few waves. The proposed method allows to assess the accuracy achieved for any given number of considered plane waves.
