Complex Permittivity Measurement of Simulated Brain Tissue for the Evaluation of Specific Absorption Rate(SAR)

Complex permittivities of human head simulating liquids were measured by a sample holder of terminated slotted coaxial line with a movable probe at mobile communication frequencies. The validity of the liquid measurement system was checked by experiments with the reference liquids. Liquids of ingredients for human brain suggested in IEEE draft and those made by the authors were measured by this slotted line system.
