Abstract: This paper presents studying for analytic and numerical methods which are used for evaluating the magnitude of electric field inside human tissues for different depths and using the most important frequencies in medical application fields, then showing the difference range between the two methods. The first method considers the human tissue as one-dimensional layered, the layers in this method modeled with non uniform transmission line. The second method is using numerical simulation CST Microwave Studio which considers the human tissues as 3D-dimensional layered. This paper also investigates the penetration for the magnitude of electric field into the phantom model of human tissues, especially into muscle tissue using different frequencies and how the electric field behaves inside the tissue when the penetration depth greater than the thickness of the tissue, as well as when the penetration depth smaller than the thickness of the tissue.
