When using electronic devices such as mobile phone, invisible electromagnetic waves are generated. These waves can be absorbed by lossy material such as human body tissues. The radio frequency field emitted from mobile phones penetrates the exposed tissues and the absorbed energy is converted to thermal energy. This thermal effect can cause harm by increasing the temperature of corresponding tissue, and damaging biological tissue, especially those of head and brain. This paper presents a critical analysis of Specific Absorption rate (SAR) at 900MHz and 1800MHz (2G-GSM) communication frequencies by considering the various gap distances between a numerically simulated human head model and source of radiation (i.e. mobile phone). It is shown here that by increasing the distance between user and mobile phone the effect of absorbed radiations can be minimized. All the numerical results are obtained by making the use of Finite Element Method (FEM).

Abstract
When using electronic devices such as mobile phone, invisible electromagnetic waves are generated. These waves can be absorbed by lossy material such as human body tissues. The radio frequency field emitted from mobile phones penetrates the exposed tissues and the absorbed energy is converted to thermal energy. This thermal effect can cause harm by increasing the temperature of corresponding tissue, and damaging biological tissue, especially those of head and brain. This paper presents a critical analysis of Specific Absorption rate (SAR) at 900MHz and 1800MHz (2G-GSM) communication frequencies by considering the various gap distances between a numerically simulated human head model and source of radiation (i.e. mobile phone). It is shown here that by increasing the distance between user and mobile phone the effect of absorbed radiations can be minimized. All the numerical results are obtained by making the use of Finite Element Method (FEM).
Author Keywords: Penetration depth, dielectric properties, finite element method, SAR, radiations.
