Uncertainty Analysis of the Rational Function Model Used in the Complex Permittivity Measurement of Biological Tissues Using PMCT Probes Within a Wide Microwave Frequency Band

Progress In Electromagnetics Research, Vol. 90, 137-150, 2009
Abstract
The PMCT probe, saying, one kind of open-ended coaxial probe adopted widely in microwave coagulation therapy of cancer, has been used to measure the complex permittivity of freshly excised specimens of normal animal tissues. The RFM model for PMCT probe is developed to extract the anticipant permittivity of specimens under test. In addition, the effects of several factors on the measurement results have been considered and discussed, including different temperature and reference materials, as well as the sampling frequency range and intervals of the rational function model. All the experiments have been conducted at the microwave frequency range from 450 MHz to 14.5 GHz.
