Abstract :
Wide-band EMF exposure is a very popular issue in the modern society. People could be simultaneously exposed by EMF with EMF of multiple frequencies from several incident directions. Tissue/ organ specified SAR varies significantly with the frequencies and incidence. This work utilizes the Chinese female anatomical model to perform FDTD simulation with frequency from 20MHz to 3GHz. SAR normalized to the WBSAR has been calculated for each tissue/organs on 12 frequencies. For each tissue/ organ, the maximal and minimal normalized SARs have also been shown. Results show that the tissue/ organ specified SAR change drastically with the frequencies and incident configurations. Comprehensive researches or simulation protocols should be studied to evaluate the human exposure by wide-band EMF.
