Özet

Reverberation Chamber is a recent and influential testing cite for the electromagnetic compatibility tests. This chamber is extensively used in these tests due to the several reasons: They ensure a large working volume and also cheaper than other test chambers. In addition, they provide statistically field uniformity that is a key indicator when undertaking a study on a reverberation chamber. In this paper, a RC with the actual dimensions has been built by the CST model and electric field strength has been calculated according to three locations of stirrer. All results in 3-dimensions are about 1dB below the proposed limit of International Electrotechnical Commission standard IEC 61000-4-21 suggestion. Observed results show that stirrer position is a predominant effect on field uniformity, and for obtaining more precise uniform electric field volume with very low standard deviations at a certain frequency or a narrow bandwidth, one needs to focus on stirrer position as well as frequency.
