DC04 - Coupling of stochastic fields into cables with non-linear loads, tests of medical equipment (WP6)
Field coupling to transmission line structures with linear loads is fairly well understood but most practical systems feature some kind of non-linearity therefore we need to find models to deal with this, also for medical imaging equipment.
The Otto von Guericke University in Magdeburg has three reverberation chambers of different sizes, a large semi-anechoic chamber and two GTEM cells (large and small), so there will be enough laboratories to perform your planned measurements. We are also just a medium-sized university in a not-to-big city, so you won’t „get lost“ and can afford the living costs.

Experimental results for stochastic EM field coupling to a non-linearly loaded single-wire transmission line above a ground plane, to a non-linearly loaded double-wire transmission line inside the working volume, to a non-linearly loaded transmission line network of single-wire lines above a ground plane, to a non-linearly loaded transmission line network of double-wire lines inside the working volume and to non-linearly loaded multi-conductor transmission lines above a ground plane as well as inside the working volume.
