Model		3 - 100 GHz exposure to FDTD numerical models and analysis of tissue heating
Details		The objective of this study was the investigation of the electromagnetic fields and resulting temperature distributions in the human body produced by exposure in the frequency range 3 GHz - 100 GHz. Analytical and numerical (FDTD) methods are used to calculate the electromagnetic field in the human skin (one dimension model) and eye (three dimensional model, rotary body). The calculations are validated with an infrared thermography measurement system. It was shown, that investigations on potential biological effects should focus to superficial tissues. Inside the eye negligible electromagnetic fields were observed. For the German and European standards a permissible power density of 1 mW/cm2 showed temperature rises in order of 0.1°C. It has to be considered, that the power densities applied in real systems are well below 1 mW/cm2 (e.g. automotive radar: 60µW/ cm2).
