Comparison of electrical parameters of human body parts with vegetation

People are concerned about the dangers that can be possibly produced by electromagnetic (EM) radiation of devices in our daily life. This concern stipulated a lot of research aimed at finding these hazards. This study is aimed to analyze electrical parameters of various parts of man, which determine the level of hazards. By using curve-fitting methods with the collected experimental data of various human tissues, smooth curves for dielectric constant, loss factor, and conductivity are obtained in terms of RF frequencies. A new parametric model was developed to describe the variation of dielectric properties originally developed for vegetation, is simulated and compared with the experimental results and Schwan´s equations. Then the similarities and differences between these approaches are discussed. Some conclusions are obtained in terms of measurable biophysical parameters.
