The studied components of this research are denominated ferrite cables and are used in most communication cabling, such as HDMI and VGA video cables. They are also present in most feeding cables for portable equipment, since its function is to avoid electromagnetic interferences or any damages caused by these on electronic devices.

The published article is called Characterization of Different Cable Ferrite Materials to Reduce the Electromagnetic Noise in the 2-150 kHz Frequency Range. It has been published in Materials magazine, which is indexed in the Journal Citation Reports (JCR).

This publication reflects the work carried out during the last months by the Professors and Researchers of the Researching Group of Digital Systems Design and Communications of the Electronic Engineering Department of the Universitat de València, as well as by the engineers of Würth Elektronik.

In this way, it appears one of the main pillars of the Chair EMC – directed by Professor José Torres: the researching. Both the Universitat de València and Würth Elektronik aim to bet for the characterization and the study of new solutions destined to the electromagnetic noise filtering.

The published results are focused on the ferrite cables characterizations in the 2-150 kHz the frequency range. This spectrum it becomes more important, as it is used by a large number of electronic devices among which stand out those destined to turn the traditional electrical grid into a smarter one (Smart Grid).

These difficulties are present on those devices that employ PLC communication through the domestic grid (Power Line Communication) to transmit information from homes and industries to centrals and sub-centrals.

Consequently, a characterization of a new filtering material based on nanocrystalline has been made, in order to determine its suitability and it has also been compared to the materials more often employed in the fabrication of ferrite cables, such as the MnZn and NiZn.

 The obtained results show the large attenuation capacity of this new electromagnetic interference filtering solution (EMI) compared to the traditional solutions and it opens a new line of researching in charge of analysing the efficiency of this material at higher frequencies.
