Abstract
Time Domain Reflectometry (TDR) probes are of interest for several applications among which geophysical ones, and in particular they can be exploited as tools for a local precise evaluation of the propagation velocity and moisture in the soil. In this contribution, some preliminary achievements regarding bifilar multilength TDR probes are presented. Previous studies have been carried out with regard to coaxial TDR probes, showing promising results, but the transfer of those results to bifilar or multifilar probes is tricky and not immediate, even if conceptually both kind of probes can be considered as electromagnetic transmission lines. In this paper, we summarise some of the problems encountered in this translation and propose strategies to overcome them in the future.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
