Statistical multipole formulations for shielding problems

[摘要] A multipole-based method is presented for modelling an electromagnetic field withsmall statistical variations inside an arbitrary enclosure.The accurate computation of the statistics of the field components from thestatistical moments of the multipole amplitudes is demonstratedfor two- and three-dimensional examples.To obtain the statistics of quantities which depend non-linearly on the field components,higher-order statistical moments of the latter are required.
