Welcome Message

The Electromagnetic Compatibility Lab is interested in the science and technology of electromagnetic compatibility, with special focus on high power electromagnetics, lightning physics and protection, and electromagnetic time reversal.

The laboratory is equipped with a semi-anechoic chamber (7 x 7 x 2.1 m) with related EMC measurement equipments (antennas, field sensors, VNAs, broadband amplifiers, etc.), a high voltage laboratory (12.8 x 12 x 7.9 m) with a 1.3 MV impulse generator and related measuring equipment. We also run a unique experimental facility at the Säntis tower for lightning measurements. The Säntis tower is instrumented using advanced equipment, including remote monitoring and control capabilities, to obtain accurate measurements of lightning currents, electromagnetic fields and optical observations.

Our Research is essentially sponsored by various programs of Swiss National Science Foundation, European Community, Swiss Electrical Utilities, European Space Agency as well as by private companies. 
We closely collaborate with many international research centers and universities among which University of Bologna (Italy), University of Florida (USA), Uppsala University and KTH (Sweden).

A new online database on extreme lightning parameters

An interactive and openly accessible online database has been established by the EPFL EMC Lab and the University of Applied Sciences IICT to present extreme values of lightning parameters. The database has been presented at the 25th Inte

Detecting short circuits by going back in time

It took EPFL researchers only three minutes to detect and locate a short circuit triggered intentionally in the power grid serving Fribourg Canton. The researchers, using a computer and a single sensor, spotted it by “going back in tim
