A DRY PHANTOM MATERIAL COMPOSED OF CERAMIC AND GRAPHITE POWDER

Details of an artificially synthesized dry phantom material developed for the experimental studies of microwave exposure to the human body a re shown. The material is solid and can simulate electrical characteri stics of high water content biological tissues such as muscles and the brain, The material is composed of high-epsilon(r) ceramic powder, gr aphite powder, and bonding resin, Any shape of phantom models can be c onstructed to simulate different parts of the body, as well as the hea d, The paper reports the synthesis technique to obtain the desired com plex permittivity and the fabrication technique of the phantom models for usage of specific absorption rate (SAR) estimation at 900 MHz.
