An Analysis of Open-Ended Coaxial Probe Sensitivity to Heterogeneous Media. [PDF]
Sensors (Basel), 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. This study presents an analysis of the coaxial probe sensing region to elucidate the effects of heterogeneities on measured ...

Effect of Open-Ended Coaxial Probe-to-Tissue Contact Pressure on Dielectric Measurements. [PDF]
Sensors (Basel), 2020 Open-ended coaxial probes are widely used to gather dielectric properties of biological tissues. Due to the lack of an agreed data acquisition protocol, several environmental conditions can cause inaccuracies when comparing dielectric data. In this work, the effect of a different measurement probe-to-tissue contact pressure was monitored in the ...

Open-Ended Coaxial Probe: Model Limitations [PDF]
IEEE Transactions on Instrumentation and Measurement, 2008 We propose a procedure to determine the validity range of any empirical model of the open-ended coaxial probe transition that is used to measure the permittivity of materials. The procedure is illustrated by an application of the method to a standard coaxial cable probe, a permittivity range of interest in the food industry and, as an empirical model ...

Analysis of an open-ended coaxial probe with lift-off for nondestructive testing [PDF]
IEEE Transactions on Instrumentation and Measurement, 1994 The open-ended coaxial probe with lift-off is studied using a full-wave analysis, and an uncertainty analysis is presented. The field equations for the following terminations are worked out: (1) the sample extends to /spl infin/ in the positive axial direction, (2) the sample is backed by a well-characterized material, and (3) the sample is backed by a

Open-Ended Coaxial Dielectric Probe Effective Penetration Depth Determination [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2016 We have performed a series of experiments which demonstrate the effect of open-ended coaxial diameter on the depth of penetration. We used a two layer configuration of a liquid and movable cylindrical piece of either Teflon or acrylic. The technique accurately demonstrates the depth in a sample for which a given probe diameter provides a reasonable ...

Open-Ended Transmission Coaxial Probes for Sarcopenia Assessment [PDF]
Sensors, 2022 We developed a handheld, side-by-side transmission-based probe for interrogating tissue to diagnose sarcopenia—a condition largely characterized by muscle loss and replacement by fat. While commercial microwave reflection-based probes exist, they can only be used in a lab for a variety of applications.

Analysis of Calibration Procedure for Open-Ended Coaxial Probe
2022 IEEE USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2022 The implementation of machine and deep learning algorithms to solve microwave related problems have been of interest to researchers. These algorithms require large amount of data to design a robust model. In this work, a cost-effective and fast method to retrieve the reflection coefficients of a material under test using the admittance model of the ...
