Abstract :
The subject of this paper is the design and performance analysis of a double-polarization transmission line (TL) device for radiated EMC tests, the CrossTEM (X-TEM) cell. The X-TEM cell is a multiwire TL device which has been specifically designed in order to optimize the test-region dimensions while ensuring double-polarization performance and suitable cross-polarization level. Cross-polarization performance is requested by the last modifications of emerging standards. Theoretical and experimental results are shown illustrating the performance of the new device. The selective-absorbing material positioning (SAMP) procedure to suppress resonances is described. The improvements experimentally achieved for both field uniformity and cross polarization are shown
