Formation of hot spots in the human eye for plane wave exposures
説明
The interaction between the human eye and EM waves in the hot spot frequency range is investigated with the aid of the FDTD method. Numerical results show that hot spots appear in a certain frequency range, and the location and number of hot spots depend on the frequencies of the incident wave. In particular, hot spot formation is found to be mainly caused by the resonance due to the geometrical structure of the eye. Additionally, temperature rises in the human eye are calculated to assess the possibilities of microwave-induced cataract formation. The numerical estimate shows that the EM wave with the power density 22 mW/cm/sup 2/ induces temperature rise 3.0 /spl deg/C, the threshold temperature rise for cataract formation.
