**3. Results and Discussion**

In this section, first the experimental results obtained will be analyzed, both in the time (*t*) and the frequency ( *f*) domains. Then, the performance of the different modeling approaches will be discussed, first in the case in which the junction itself is represented by a zero-dimensional element, and secondly in the case in which the staggered mesh method is used to provide a quasi-3D description of the junction.
