Temperature Variation by Electromagnetic field in Tissue: Effects of Electromagnetic Radiation on Tissue Temperature

Abstract

The Electromagnetic radiation is of increasing importance in the study of biological characteristics variation, When more complex heterogeneous object like skin with nonflat surface are radiated the additional picks in the surface field pattern are possible .In order to have deep understanding about the effect of biological cells the theoretical analysis of heat transfer in the tissue is essential, Now we analyze the single dimensional heat transfer equation. This analysis determines the effect of thermal convocation due to blood flow and transfer of heat from tissue surface into space, for microwave in the 2 GHz to 10GHz range. The increase in tissue surface temperature is 3◦C for 10 GHz with 100 mw/ cm2. The maximum increase in tissue temperature in an animal exposed to the “safe” microwave field of 10 mw/ cm2 is upto 1◦C.
