Popis: The power absorbed by human head tissues in the microwave range is investigated. Calculation of the electric field induced in the head tissues by antenna probe is based on the use of the Green’s functions of the stratified media. Two types of emitters such as a half-wave dipole and a loop antenna are compared in terms of the depth of electromagnetic energy penetration. The power absorbed by different layers of the human head model is calculated. The conclusion is made on the best efficiency of antenna with an annular current, such as a flat helix. The effect of the conducting screen on the efficiency of the antenna is studied. The data were obtained for designing effective field sensors for the microwave radiometry of the brain.
