The absorption of energy by human external tissue when HF irradiation and the physical consequences involved are the purposes of this study. When it is directed toward the surface of the skin, energy is transmitted to its inner layers causing an increase of the temperature. This process has experimentally been proved to be beneficial in many cases. Yet theoretically there is still a slightly hollow basis about it. Skin tissue is actually a multilayer tissue with a different characteristic in each layer. Each one of them is characterized by some parameters, such as permittivity, conductivity, density and specific heat. Two kinds of skin tissues will be analyzed: a fibrous and a fatty one, each of both with a different skin humidity. Our model takes into account the heating by HF radiation, the redistribution of energy through the tissues and the cooling rate by blood in order to predict the increasing of tissue temperature in differents situations.
