Abstract:
The assessment of the fields induced in biological tissue by an electromagnetic (EM) wave is a major issue, not only for its relevance in medical research, but also for its implications on the setting of industrial standards. This paper describes the analysis of electromagnetic (EM) absorption properties of biological multilayered structure. The biological structure comprises three different tissues of skin, fat and muscle. A step-by-step approach for the computation of the EM fields within the multilayered structure is presented. The estimated specific absorption rate (SAR) distribution in tissues due to exposure from plane waves of frequencies 433, 900, 1300, 1800, and 2450 MHz, based on an incident power density 4.5 [mW/cm2], are also presented.
