This paper analyzes the performance of a reverberation chamber when the working volume (WV) is positioned inside the stirrer rotating volume. More precisely, considering a very large stirrer, its inner surface and axis are removed to gain a large space to be used as WV. The design of this new WV position and stirrer shape is done using our finite-difference time domain code, previously optimized for reverberation chamber simulations and tested with experimental results. The proposed setup increases the WV and improves the reverberation chamber behavior with respect to a traditional setup. Moreover, it needs just one motor to control the stirrer, and it does not require more complex mechanical part.
