Electromagnetic Time Reversal for Radiating Source Identification in Time Domain

“…In fact, the main idea is reversing signals in time by making the electromagnetic waves back-propagate to their initial source [15]. Actually, this technique is widely developed in the frequency domain using the Decomposition of the TR Operator (DORT) [16]. Due to the frequency method limitations, the use of the time domain is more and more adopted.…”

Soft Fault Diagnosis in Wire Networks Using Time Reversal Concept and Subspace Methods

“…Although, soft faults might not appear dangerous in their early stages, their potential degradation with time might end up with hard faults leading to catastrophic consequences. With this in mind, we focused our research efforts on dealing with such kind of faults due to their critically difficult detection, especially in complex wire networks [5]- [8]. Accordingly, guaranteeing a trustworthy usage of cables necessitates investing in the research and development of techniques qualified for precisely detecting the presence of faults in wire networks.…”

“…Within this context, TR-based methods were adopted to solve the problem of detecting and locating soft faults in different complexity cable networks [5], [11], [12]. Notably, DORT method, a TR variant standing for decomposition of the TR operator, contributed significantly in the precise location of single and multiple soft faults in complex NUTs [6]- [8].…”
