“…Moreover, there have been some experiments carried out to confirm that one pulse can be decomposed into several pulses with lower amplitudes because of different modal delays in the structure [13], with approaches to apply modal phenomena for protecting critical equipment against the effects of UWB-pulses propagation being described [14]. Experimental results on flat cable have demonstrated the possibility of contactless wire diagnostics using modal probing even without galvanic connection to the wire [15]. The obtained results have demonstrated the possibility of developing new devices fordetecting, identifying, and diagnosing electrical connections.…”

This paper presents a unified description of a new approach for contactless detection, identification, and diagnostics of electrical connections and describes an idea and principles of using modal probing for these tasks. Simulation and experimental results on pulsed signal propagation through flat cables demonstrate the modal decomposition of a pulsed signal, which varies depending on the state of the probed wire. It is shown that the presented tasks can be solved by modal probing. The article also considers the analysis of modal distortions in frequency domain and gives the formula for its practical use. This formula can be useful when the pulse duration time is longer than the minimum of mode delay difference. In conclusion, we present further development ideas of the modal probing.

“…The peculiarities of their interaction were partially considered in papers (Senthinathan et al, 1987;Muthana and Kroger, 2007). However, an additional study can help discover new regularities in the behavior of these lines' dependencies, in particular, useful modal phenomena, similar to the ones suggested for printed (Gazizov et al, 2012a;b) and cable (Gazizov et al, 2009;Gazizov and Zabolotsky, 2012;Orlov et al, 2013) structures.…”

Dielectric fill features may have a significant effect on the characteristics of both the cable and microstrip transmission lines. It is necessary to provide proper characteristic impedance of microstrip transmission lines to create a multi-layer printed circuit boards with digital, analog and RF circuits. The authors simulate the impact of the planar location of two conductors in a dielectric material above an ideally conducting plane on the board delays per unit length of transmission-line modes. The simulation showed the dependency of even and odd modes and their differences on the distance between the conductors during the change in the depth of immersion of conductors into the dielectric material. The behavior of obtained dependencies was explained. It was discovered that the difference of board delays changes sign and reaches high values (from -0.8 to 1.5 ns/m) with close coupling. Obtained results can be used for further research in the field of electronics. In particular, for model filtering development based on microstrip lines. This will reduce the level of the ultrashort pulses problem.
