Experimental Investigation and Mathematical Modeling of Design Parameters for Efficient Stirrers in Mode-Stirred Reverberation Chambers

Reverberation chambers a la carte: An overview of the different mode-stirring techniques

“…Considering the case of rotating paddles, the stirring efficiency depends on paddles size, rotating volume, and eccentricity [17], [18], and an optimization leads to better performance [10]. Typically, the stirring efficiency is enhanced by enlarging the paddle dimensions as much as possible, even though this could lead to a progressive reduction of the WV available for testing.…”

The Role of Losses in the Definition of the Overmoded Condition for Reverberation Chambers and Their Statistics

“…Since this theoretical result is based on the assumption of a well-stirred cavity, the limited efficiency of the stirring technique is often regarded as the most likely source of noncompliancy, especially in the lower frequency range, because of the statistical correlation of contiguous stirrer positions [7].…”

Reverberation chamber as a statistical relaxation process: Entropy analysis and fast time domain simulations

“…Many papers in the reverberation chamber (RC) topic were addressed to enhance its performance, changing the stirrer shape and dimension. The rotating volume, the size, and the eccentricity of the paddles were theoretically investigated in [7], whereas in [8] heuristic formulas were given to derive stirrer efficiency starting from experimental observations. In [9] the peripheral part of the stirrer blades that gives the main contribution in generating uncorrelated samples is analyzed.…”
