Direct broadband microwave characterization of biological tissues using the coaxial probe technique

A key advantage of using coaxial probe for microwave characterization of biological media is the non-invasive nature of the technique. The complex permittivities of normal tissues from animals and both normal and cancerous tissues from human bodies were measured over a broadband microwave region with this technique. The biological tissue measurements showed that the complex permittivities measured by this technique are in good agreement with other investigations. This is a cost effective, non invasive and easy to use technique which makes it very suitable for diagnostic and therapeutic applications of microwaves in biomedicine.
