Abstract :
Human eye model having a prolate spheroidal shape composed of lossy dielectric medium is considered in Presence of plane electromagnetic waves. Frequencies of 750 MHz 1.5 GHz were used to find the distribution of the time averaged absorbed power density along the three orthogonal axes of the model.For a plane wave having electric, magnetic and cross polarizations, the total time- averaged absorbed power density is estimated at different frequencies. Further the temperature increase due to microwave radiation is estimated as a function of time duration of exposure. An extended integral equation method and numerical solutions approach is used to estimate the Scattering Cross-Section of this model. This extended boundary condition approach is used for prolate spheroidal shape of human eye having a complex dielectric constant. Absorption of electromagnetic energy at millimeter wave length is estimated for this proposed model of human eye. Computer results using DEC-2050 are obtained and discussed particularly for millimeter wave electromagnetic radiation.
