Abstract :
Human eye being unprotected by the layer of skin and bones is one of the most sensitive organs to EM radiation. The absorption of EM radiation is quantified in terms of SAR and to calculate the SAR the knowledge of complete electric field distribution inside the eye is necessary. In this paper the problem of distribution of near EM field inside an eye is considered as EM scattering problem. Human head is considered to be in the air, thus it represents an open boundary problem, as well. The method for obtaining electric field distribution inside the eye is novel hybrid BEM/FEM with discontinuous boundary elements
