Numerical study of the behavior of the electromagnetic field its relation to the energy absorbed by a human head exposed to a radiofrequency (RF) source application: the cellular

Abstract

In this part of our modest work, we have numerically studied the behaviour of the electric and magnetic field interior the human head exposed to an RF (cellular) source. For this study, an electromagnetic field coupling was established between an RF source and the human head. to solve the system of equations a finite element formulation coupled with the boundary integral formulation which is adopted, the results obtained are presented in the form of arrows with colors depending on the intensity of the electric field ⃗. From where we can calculate the intensity of the electric field interior the human head, which allows us it possible to calculate the electromagnetic energy absorbed by the human head from where we can also calculate the SAR interior the human head, and make a comparison with the SAR measured at the edge of the human head, and finally the proposal of a solution for the minimization of the energy absorbed by the human head with the introduction of an interface between the human head and the RF source, and a well determined the clear selection of interface materials has been done.
