COMPUTATION OF SUCCESSIVE ABSORPTION RATE IN BRAIN USING SIMULATION OF ELECTROMAGNETIC RADIATION - FDTD METHOD

C. K. Smitha, N. K. Narayanan

Abstract: Electromagnetic absorption in brain due to mobile phone radiation is measured as Successive Absorption Rate (SAR). The SAR can be computed in terms of magnitude of Electromagnetic radiation (EMR) in brain. The magnitude of EMR is simulated using Finite Difference Time Division (FDTD) method since it could not be measured directly. FDTD method is a numeric method in time domain, obtained from the Maxwell equations in differential mode. Generally the mobile phones have an output power less than 1W and emit radiations ranges from 900MHz to 2200 MHz. So we simulate the experiment for two frequencies (900MHz and 1800MHz) with two powers (0.6Wand 1.2 W). The value of SAR at 900MHz and 1800MHz d for input powers of 0.6W and 1.2 W are computed using this method
