Dielectric sensors are a popular choice for soil moisture determination. However, the output
of many of these devices, especially those operating at frequencies in the MHz range, can …

Due to the spurious peaks caused by multireflection and the randomness of the cable
transfer function, the frequency domain reflectometry (FDR) method based on Fourier …

The phase of the reflected wave at the defect can characterize the change type of the defect.
The frequency domain reflection (FDR) method can be used to locate cable defects based …

This article presents a time domain transmissometry soil moisture sensor (TDT-SMS) using a
dispersive phase shifter (DPS), consisting of an interdigital capacitor that is loaded with a …

There is a growing demand for using non-destructive geophysical techniques to internally
image dam condition and facilitate the early detection of anomalous phenomena. Near …

High-temperature superconducting (HTS) cables are expected to be installed in cable
tunnels that are already constructed in urban districts. Therefore, the installation of normal …

An innovative self-referencing time-domain reflectometry (TDR) dielectric spectroscopy
method is introduced. The method extracts the first reflection from a mismatched section …

Most sensing networks rely on punctual/local sensors; they thus lack the ability to spatially
resolve the quantity to be monitored (eg a temperature or humidity profile) without relying on …

Complex dielectric spectrum sums up the electrical properties that can infer a material's
composition. Among various dielectric spectroscopy methods, time-domain reflectometry …

This work presents a low-cost, compact-size and highly sensitive sensor based on a
Reconfigurable Phase Shifter (RPS) that is designed, simulated, fabricated and tested using …
