Open-Ended Coaxial Probe for Dielectric Property Measurements in Sugar Mills
2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019 In the Australian sugar industry, the potential output from the mill and the value of a sugarcane crop is dependent on factors such as the concentration of sugar in the juice and its soluble solids content. Current quality assessment techniques used in the industry are labor intensive and time consuming, preventing them from being used for process ...

Detection of Diseased Tissues with Open-Ended Coaxial Probes
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021This work presents analysis of open-ended coaxial probes having four different aperture sizes. The probes are simulated in CST. S-parameters collected from simulations and the dielectric properties of the material under test is retrieved with an in-house algorithm. The probes are fabricated and the measurements are performed with the known materials to

On the Dielectric Measurement of Thin Layers Using Open-Ended Coaxial Probes
IEEE Transactions on Instrumentation and Measurement, 2021Using an open-ended coaxial probe and a vector network analyzer (VNA) is a conventional technique for the noninvasive and broadband measurement of dielectric permittivity. The method is widely applied to characterize bulk material and liquids and has recently been extended to thin sheet material samples. However, it is commonly believed that the method

Dimensional analysis of an open-ended coaxial-line probe
IMTC 2001. Proceedings of the 18th IEEE Instrumentation and Measurement Technology Conference. Rediscovering Measurement in the Age of Informatics (Cat. No.01CH 37188), 2002Open-ended coaxial-line probes provide a convenient means of determining the dielectric properties of many materials over a relativity wide frequency range. Because of this, much attention has been given to understanding the interaction of the probe and the material it is inserted into.

Admittance models for open ended coaxial probes and their place in dielectric spectroscopy
Physics in Medicine and Biology, 1994Starting from a rigorous formulation for the admittance of an open ended coaxial probe, this paper identifies the simplifying assumptions that are introduced to obtain more practical solutions. The predictions of the models are compared to each other and to experimental data obtained on an independently calibrated experimental set-up.

Open-ended coaxial probe measurements for breast cancer detection
2010 IEEE Radio and Wireless Symposium (RWS), 2010We have simulated and experimentally tested a coaxial probe measuring system to be used in distinguishing between normal (healthy) breast tissue and cancerous (often malignant) breast tissue. The system employs commercially available components including an Agilent 8363B phase network analyzer (PNA) and an Agilent 85070D dielectric probe.

Miniature open-ended coaxial probes for dielectric spectroscopy applications
Journal of Physics D: Applied Physics, 2006In this paper we describe theoretical modelling and experimental measurements of miniature coaxial probes with flat and conical end profiles, suitable for dielectric spectroscopy measurements on biological tissue samples. Various analytical solutions are compared with the results of simulations using CST Microwave for the sub-millimetre diameter probes
