Many different phantoms have proposed as the human head model for experimental estimation of the interaction between the human head and electromagnetic fields around. In this report, a solid phantom is introduced as the human head model realizing the same relative dielectric constant and conductivity as brain tissue. This brain-equivalent solid phantom makes it possible to accomplish highly reliable and precise estimation of specific absorption rate (SAR) in biological tissue. Brain-equivalent solid phantom models of cubes and spheres are fabricated. Measurements are performed to estimate the SAR in the human head models exposed to microwave sources by using the thermographic method.
