—PCB-level shielding enclosures differ from the other shielding products in several aspects due to their small volume and therefore pose new challenges to the evaluation of performance. This paper describes several possible approaches to accomplish fast and reliable shielding effeciteness (SE) values.
—This paper reports the results of two experimental campaigns aimed at studying the high-frequency response of a raceway containing low voltage power, telephone, and Ethernet cables, to external electromagnetic field illumination. The raceway was tested against HPEM transients inside a gigahertz transverse electromagnetic (GTEM) cell and low-power fields… (More)
Pantograph arcing is the main electromagnetic interference source in electric railways. A series of measurements of the radiated power of pantograph arcing has been taken in a reverberation chamber by using a laboratory replica designed to simulate the arcing pantograph. The radiated power properties are investigated in different resolution bandwidths, arc… (More)
We have analysed the performance of multimode antennas arrays in double directional finite scatterers channel model with and without mutual coupling and compared the results with Omni directional antenna arrays. We have shown that multimode antennas are more suited as array elements as they perform better with regards to capacity and spatial correlation as… (More)
