Dosimetry Evaluation and Tissue Structure Dependence of Localized Peak SAR inside Head Model for 1.5GHz Microwave Far-field Exposure

摘要

We investigated the relationship between the constituent tissue number and the localized peak SARs (spe- cific absorption rate) inside an our newly developed MRI (Magnetic Resonance Imaging) based head model for far-field exposure with respect to all irradiating directions of the microwaves being employed for portable telephones. The FDTD (Finite-Difference Time-Domain) method was used to compute the SARs inside the MRI based head models consisting of various tissues up to fifteen kinds for 1.5GHz microwave far-field Exposure of 1 mW/cm~2 specified in an uncontrolled environment.
