Research and Testing of Tissue Simulating Materials

The topic for this thesis was commissioned by Verkotan Oy. Verkotan Oy is providing testing and consulting services at the wireless industry. The aim of this thesis was to determine mixtures that simulate dielectric properties of the human or animal tissue at larger frequency ranges than the known mixtures and analyze the possibilities of ballistic gel to simulate electrical properties of different parts of the human body. Other part of the thesis was to learn the principles of measuring instruments that can be used to measure the dielectric parameters of the materials. The work on this subject started by researching tissues dielectric properties and materials that can be used in the mixtures. Recipes found in the research were manufactured and tested. Many recipes were found in research at different frequency ranges and some of the recipes were tested in practice. Experiments showed that tissue simulating gel is capable of simulating different parts of the tissue dielectric properties at least at known frequency ranges
