Integrating Complex Permittivity Measurements with Histological Analysis for Advanced Tissue Characterization [PDF]

open access: yesSensors
We developed a measurement setup and protocol reliably relating complex permittivity measurements with tissue characterization and specific histological features. We measured 148 fresh human tissue samples across 14 tissue types at 51 frequencies ranging

Dielectric Characterization of Small Breast Biopsy Via Miniaturized Open-Ended Coaxial Probe

open access: green2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI), 2022
The classification between normal and malignant tissues based on the use of an open-ended coaxial probe reveals an advantageous rapid support to traditional biopsy. The present work proposes an assessment of small biopsy breast dielectric characterization with our custom-designed open-ended coaxial probe.

Dielectric Characterization of Biological Samples by Using an Open-ended Coaxial Probe

open access: green2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020
The present work proposes the use of a miniaturized open-ended coaxial probe to perform the detection of normal and malignant biological tissues, typically resulting from an excisional biopsy. The system has been numerically designed by analyzing a biological specimen having spherical shape and by varying its diameter, accordingly.

Analysis of Calibration Procedure for Open-Ended Coaxial Probe

open access: yes2022 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 ...
