The Study of Biological Effect of EM Radiation by Antenna at Different Position of Human Model

This paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. When a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near of Thai). It is similar to that of cooking in the Microwave oven. The finite difference time domain (FDTD) method is widely used as a computational tool to simulate the electromagnetic wave propagation in biological tissues. The FDTD method has been used for calculating SAR (specific absorption rate) values on human model by varying the EM radiation at frequency 1.47 GHz.
