Hybrid BEM/FEM edge element computation of the thermal rise in the 3D model of the human eye induced by high frequency EM waves

摘要

This paper investigates the thermal rise in the human eye caused by EM wave exposure at frequencies of 1 GHz, 2 GHz, 4 GHz and 6 GHz. The power density of the incident plane wave is 10 W/m². Because an eye under the influence of EM wave is unbounded EM scattering problem the method used for the computation of EM fields inside the 3D model of an eye is hybrid BEM/FEM using edge elements. It has been found that the hot-spot formation of EM field intensity inside an eye exist at frequency range of several GHz, whereas at frequency of about 6 GHz and above, the most dominant effect of EM fields occur at the surface of an eye.
