Electromagnetic Radiation Effects of Radio Frequency Source on the Human Body | Chapter 12 | Technological Innovation in Engineering Research Vol. 4

 

The current investigation confirms that energy lost in the human skull varies with both the distance between the head and the electromagnetic source and with changes in the properties of the surrounding medium. Mobile phone usage is increasing rapidly. Our concern is the electromagnetic field coupling between the biological tissue and the radio frequency power source (human head). This issue was solved using a system of equations and a finite element formulation that was combined with a boundary integral formulation that was used with the system. An integral formulation based on the boundary integral approach may be used to determine the electromagnetic field at any location of the inner medium and the surface. With the help of this technique, we are able to determine the RF energy at each location within the inner medium (the human head), based on the specifications of the outside medium, and select the ideal material for the implementation of the interface. The study of the open field problem is made possible by the accurate modelling of electromagnetic wave propagation in the dielectric medium and the application of the absorbing condition.
