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.

“…The classical formula 6 f 0 (f 0 is the empty cavity cut-off frequency) (Mitra & Trost, 1997) is used. Chamber walls as well as the stirrer are taken to be perfectly conducting, so that the boundary condition is that electric field tangential components are equal to zero on their surfaces.…”

In this article, angular plane wave expansion of the standing electric field within a reverberation chamber is studied. For this purpose, a high-resolution Root multiple signal classification based method was adapted to the context of the reverberation chamber by using a decorrelation procedure to estimate the angles of arrival and complex amplitudes of the planes waves. Using finite difference time domain simulations to get the standing electric field cartographies, it is demonstrated, at low frequencies, that directions of arrival are slightly affected by the stirrer rotation, whereas the wave amplitudes are strongly perturbed. This result indicates that the stirrer works as a plane wave powers tuner.

“…Their operating range of frequency is above a minimum frequency, coined the lowest usable frequency (LUF). Above the LUF, the electromagnetic fields are supposed to be statistically isotropic, uniform and depolarised on a stirrer rotation [3][4] [5]. These statistical requirements are naturally fulfilled by most modes of a chaotic cavity [6] [7].…”

Using the knowledge gained from the wave chaos theory, we present simple shapes of resonant cavities obtained by inserting metallic hemispheres or caps on the walls of a parallelelipedic cavity. The presented simulation results show a significant improvement of the field statistical properties when the number of hemispheres or caps increases, and the comparison with a classical reverberation chamber geometry shows a better homogeneity and isotropy can be attained using these new proposed shapes.Index Terms-Chaotic cavity, field homogeneity, field isotropy, reverberation chamber, statistical distribution.
