Electromagnetic Field Chaoticity Enhancement in Reverberation Chambers

The paper analyzed the benefits obtained in the reverberation chamber performance when proper diffractors and tilted walls are added to the geometry. By destroying the regularity of the boundary conditions the chaoticity of the electromagnetic field is enhanced. A home made FDTD code, running on supercomputers, is adopted to compute the field inside the RC and for its statistical analysis. Performance indicators such as the field uniformity, the independent chamber state number, are improved in a chaotic RC. The narrowband uncorrelation drops, typical in non-chaotic RCs, are strongly mitigated.
