Abstract
Phantoms that exhibit complex dielectric properties similar to low water content biological tis- sues over the electromagnetic spectrum of 2-3 GHz have been synthesized from carbon black powder, graphite powder and polyvinyl-acetate-based adhesive. The materials overcome various problems that are inherent in conventional phantoms such as decompo- sition and deterioration due to the invasion of bacteria or mold. The absorption coefficients of the materials for various compositions of carbon black and graphite powder are studied. A combination of 50% polyvinyl- acetate-based adhesive, 20% carbon black powder and 30% graphite powder exhibits high absorption coeffi- cient, which suggests another application of the mate- rial as good microwave absorber for interior lining of tomographic chamber in microwave imaging. Cavity perturbation technique is adopted to study the dielec- tric properties of the material.
