Complex Permittivity Measurement as Imaging Method

Popis výsledku v původním jazyce

Complex permittivity measurements are important in microwave engineering, material processing, as well as biomedical applications. Probe for measuring the complex permittivity of biological tissues has been adapted from a standard RF connector for coaxial cable, called N-type connector. The original proposed range of application was fBW = 1 GHz. A typical measurement setup using the reflection method on an open-ended coaxial line consists of the network analyzer, the coaxial probe and software. Our measurements were done with the aid of Agilent 6052 network analyzer in the frequency range from 300 MHz to 3 GHz. First the calibration of the vector network analyzer is performed. Then the calibration using a reference material is done. Finally, the reflection coefficient of material under test is measured. The complex permittivity of material under test is evaluated by the MATLAB. The initial measurements on the inhomogeneous agar phantom were performed.
