A numerical analysis of temperature elevation in a rabbit ocular with localized and uniformed exposure conditions at 60 GHz

A numerical dosimetry was performed for a rabbit ocular exposure by 60-GHz millimeter wave in this study. We compared calculated temperature elevation between localized exposure by a lens antenna and uniformed exposure by plane wave. Here, incident power density was normalized against spacial average of incident power over the surface of cornea according to the previous study. The peak incident power density of the lens antenna was 5.3 times higher than that of the plane wave. Therefore, the maximum temperature elevation by the lens antenna exposure was higher than that by the plane wave exposure. Thus, possibility was shown that threshold incident power density for ocular injury with the lens antenna exposure becomes lower than that with the plane wave exposure.
