In this paper, the part microwave coagulation therapy (PMCT) probe is used for calibration and measurement. Two reference liquids are measured and the reflection coefficients are recorded and calculated, the rational functional model (RFM) coefficients for PMCT probe are then calculated and compared in two cases of different reference liquids. We may note that, within a wide frequency range, saying,...
The resonant cavity perturbation technique is usually used to measure the complex permittivity of various dielectric materials at microwave frequency. The real and imaginary part of the complex permittivity of the material under test can be extracted from the measured resonant frequency shift and the change of quality factor (Q factor) of the resonance cavity with inserted samples. In this paper,...
This paper presents the revised techniques used both in in-vitro and in-vivo measurement of dielectric constant of biological tissues. The in-vitro technique introduces a revised perturbation technique through a RW cavity while the in-vivo measurement is implemented by a revised coaxial monopole antenna used in microwave coagulation therapy of liver cancer- PMCT probe. Both the advantages and disadvantages...
