Abstract

The main original contribution in this thesis is the novel application of microwave open-ended coaxialprobes in the characterisation of the electrical properties of normal and cancer tissues, and their use for cancer therapy. In terms of the cancer diagnosis part, thisthesis showsthe design, analysisand realization of new open-ended microwave sensors with a needle aperture to assess their sensitivity and usefulness for microwave characterizations of materials. These needle-type sensors are capable of penetrating easily into semi-solid and multilayered material. This is very important in cancer diagnosis since they permit non-destructive measurement, with the advantage of using them as medical needles that have higher sensitivity at low frequencies than the usual flat aperture probes. Moreover, the sensors have been developed to measure properties of normal and cancer tissues for early cancer detection applications. In terms of the cancer treatment part, a novel non-thermal microwave irradiation technique has been adapted and developed for complete annihilation of cancer cells with a limited peak temperature of 42°Cand short treatment time of 5 minutes.
