Reflection and Transmission Coefficients of Different Biological Tissues

Y. Ratna Kumar , Prof. G.S.N. Raju

The Electromagnetic waves show different characteristics of different homogeneous materials. As Electromagnetic waves incident on a perfect conductor they are entirely reflected, whereas on good conductor they are completely transmitted. But one incident on a medium which is neither a good conductor nor a good dielectric they are partially reflected and partially transmitted. In case of a non-homogeneous media like human body the reflection and transmission coefficients, depending upon permittivity, conductivity, permeability and frequency, vary in different tissues. So that it is complex to estimate the characteristics of Electromagnetic waves. In this paper, the analysis is made and the data on reflection and transmission coefficients of few biological tissues is presented.
