The Role of Probe Attenuation in the Time-Domain Reflectometry Characterization of Dielectrics [PDF]

open access: yes, 2010
The influence of the measurement setup on the estimation of dielectric permittivity spectra from time-domain reflectometry (TDR) responses is investigated.

Coaxial atomic force microscope probes for imaging with dielectrophoresis [PDF]

open access: yesApplied Physics Letters, 2011
We demonstrate atomic force microscope (AFM) imaging using dielectrophoresis (DEP) with coaxial probes. DEP provides force contrast allowing coaxial probes to image with enhanced spatial resolution. We model a coaxial probe as an electric dipole to provide analytic formulas for DEP between a dipole, dielectric spheres, and a dielectric substrate.

Size Miniaturized Coaxial Probe Fed Antenna for Multiband Applications

open access: yesAdvanced Electromagnetics, 2020
A novel coaxial cable-fed antenna with a combination of L-shaped elements is proposed for multiband applications. The obtained resonances at different frequency bands are realized by adding L-shaped strips with different lengths to the antenna geometry ...

A Numerical Investigation of the Dispersion Law of Materials by Means of Multi-Length TDR Data

open access: yesRemote Sensing, 2022
In this paper, we propose a method for retrieving the dispersion law of a material under test from multi-length TDR measurements in reflection mode, repeated at several frequencies.

Dielectric Characterization Improvement of Biopsy Samples Via a Coated Open-Ended Coaxial Probe

open access: yes, 2022
In the present work, we investigated the dielectric characterization of cylindrical shaped tissues via an open-ended coaxial probe. So long as biological tissues are not stiff, in this contribution we look for the minimum cylinder diameter and the ...

Strain Sensor from Tapered Fibres [PDF]

open access: yesEPJ Web of Conferences, 2020
A new all fibre, and low transmission loss, digital optical strain sensor is proposed. This sensor behaves as a Coaxial Mach-Zehnder interferometer. Special depressed cladding single-mode fibre DCF was tapered down to the micrometer scale presenting FSR ...
