An Analysis of Open-Ended Coaxial Probe Sensitivity to Heterogeneous Media [PDF]

open access: yesSensors, 2020
Open-ended coaxial probe spectroscopy is commonly used to determine the dielectric permittivity of biological tissues. However, heterogeneities in the probe sensing region can limit measurement precision and reproducibility.

Thickness estimation of the subcutaneous fat using coaxial probe. [PDF]

open access: yesHealthc Technol Lett, 2016
In this Letter, a non-invasive method for thickness estimation of the subcutaneous fat layer of abdominal wall is presented by using a coaxial probe. Fat layer has the highest impact on the averaged attenuation parameter of the abdominal wall due to its ...

Cervical Tissue Hydration Level Monitoring by a Resonant Microwave Coaxial Probe [PDF]

open access: yesSensors, 2022
Cervical tissue hydration level is one of the most important parameters to monitor in the early diagnosis of preterm birth. Electrical-impedance-spectroscopy-based techniques are often used, but they suffer from limited accuracy.

Comparison of Metal-Backed Free-Space and Open-Ended Coaxial Probe Techniques for the Dielectric Characterization of Aeronautical Composites [PDF]

open access: yesSensors, 2016
The trend in the last few decades is that current unmanned aerial vehicles are completely made of composite materials rather than metallic, such as carbon-fiber or fiberglass composites.

Predicting the sensing radius of a coaxial probe based on the probe dimensions

open access: yesIEEE Transactions on Antennas and Propagation, 2021
The coaxial probe technique is used to acquire the dielectric properties of biological tissues in the microwave frequency range. To dielectrically characterize heterogeneous samples, the sensing radius of the probe must be known.

Modelling the Sensing Radius of a Coaxial Probe for Dielectric Characterisation of Biological Tissues

open access: yesIEEE Access, 2018
The open-ended coaxial probe is the most common measurement tool used to dielectrically characterize biological tissues. Most healthy and malignant biological tissues are macroscopically heterogeneous, with the exception of a few tissues, such as liver ...
