千兆赫TEM（GTEM）室是一种特殊的TEM设备，用于高达1 GHz及以上的发射和抗扰度测试。根据IEEE EMC会议上的评论和建议，并包括国际标准化组织的几个成员的建议，进行了一项非常实用且具有挑战性的实验。GTEM 1750的电场结构在高达1千兆赫的测试体积内的许多相关点中得到了进一步研究。已经测试了空电池以及负载电池。被调查的盒子是一个30厘米的金属立方体。从计算机模拟中获得了更多的支持，从而得出了更详细的实地等高线图。在此基础上，对现有GTEM室进行了一些改进和改造。
The Gigahertz TEM (GTEM) cell is a special TEM device that is used for both emission and immunity testing up to 1 GHz and above. Based on previous comments and recommendations in IEEE EMC sessions and including suggestions from several members of international standardization groups a very practical as well as challenging experiment was conducted. The E-field structure of a GTEM 1750 has been further investigated in a number of relevant points within the test volume up to one Gigahertz. An empty cell as well as a loaded cell have been tested. The box under investigation was a metal cube of 30 cm. Additional support was gained from computer simulations, leading to more detailed field contour plots. Based on this work a number of improvements and retrofits for existing GTEM cells is given.
