Frequency Dependent Attenuation of EM Radiation on Biological Tissues

Abstract

The human body is a non-homogeneous medium and it is characterized by different fundamental parameters. All of them vary from location to location. Human body acts as a transmission medium for electrical signals. This offers novel data communication in biomedical monitoring systems. The human body is characterized as a transmission medium for electrical current by means of numerical simulations and measurements. Several attempts have been made to model the human body as electrical channel. Here the variations of penetration characteristics of the Electromagnetic radiation of the biological tissues had been observed.
