Spatial-correlation functions of fields and energy density in a reverberation chamber

A plane-wave integral representation is used to derive spatial-correlation functions for the complex electric and magnetic field components, and the results agree with previously published results derived by volume averaging of a mode sum. Results are also presented for the correlation functions of squared electric and magnetic field components and electric, magnetic, and total energy densities. The theory for the spatial correlation function of the squared transverse electric field is shown to agree well with published measurements of the power received by transverse monopole antennas.
