Investigation of the effect of obliquely incident plane wave on a human head at 900 and 1800 MHz

This article investigates the effect of obliquely incident plane wave on a multilayered structure representing a simplified model of the human head at a frequency of 900 and 1800 MHz. Exact formulas for the electric field within the structure are derived. The maximum power dissipation and its dependence on the frequency and dielectric parameters are presented. Using these results, the local specific absorption rate is calculated, plotted, and compared with international levels. © 2009 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2010.
