Investigations on the Penetration Properties of Electromagnetic Waves in Biological Media

Interaction of Electromagnetic radiation with the human body is a complex function of numerous parameters. The electromagnetic radiation is characterized by its frequency, intensity of electric and magnetic fields, their direction and polarization characteristics in free space. The fields inside the tissues of biological bodies can interact with them and therefore it is necessary to determine these fields for any meaningful and general quantification of biological data[4] obtained experimentally or theoretically. This data is very useful in the treatment of tissues, usually, EM energy at specified frequencies. As this requires knowledge of the penetration characteristics through a conducting media, variations of depth of penetration for various tissues are obtained.
