| Abstract: | This article introduces the requirements for the electromagnetic field uniformity in IEC 61000-4-20 and two methods are used to analyze the field homogeneity of the uniform area of the GTEM cell which are recommend by Annex B in IEC 61000- 4-20. The authors found two methods possibly result in two different conclusions to validate whether the uniformity of the GTEM cell can be meet the requirements of 61000-4-20. The cause of different conclusions is analyzed and some suggestions are given in the end. |
