“…to refocus electromagnetic waves by reversing in time the response signals of a system [13]- [16]. Although the TR shows to be efficient at identifying temporal sources at a unique point in the medium and at the focusing instant only, its performance unfortunately weakens when imposing complex conditions on the duration or the profile of the refocused electromagnetic field [17]. Moreover, TR applicability becomes unsteady when applied in lossy or constrained environments due to the poor refocusing quality of the back-propagated signals [18], [19].…”

This paper is dedicated to experimentally validating the Linear Combination of Configuration Field (LCCF) method in transmission-line networks. The LCCF is first modified to comply with some physical limitations encountered during experimentation, then tested to identify the temporal profile of voltage/current sources that would lead to specified voltage/current signals over a definite time interval at few points of a transmission-line network. In another experimental validation, when faults appear in some lines of these networks, the LCCF is also tested to bring an electrical correction that compensates for the effect of the potential faults regardless of the number, nature, and position. For this latter, soft and hard faults are considered. The LCCF method paves the way for the development of new instrumentation in generating and conditioning temporal signals.
