Abstract

The next-generation mobile communication technology may exploit the higher frequency spectrum beyond 100 GHz, while most studies on electromagnetic field (EMF) exposure from mobile communication devices focus on frequencies below 100 GHz. In this paper, the EMF exposure from sub-terahertz antennas designed for future mobile communication is evaluated with a multilayer flat tissue phantom. It is demonstrated that the deposited EMFs can be evaluated by neglecting the deep tissue in the simplified phantom. Then, the temperature distribution in the full-size phantom can be evaluated using the solution to the simplified electromagnetic problem to reduce the overall computation time. Considering different sizes of the averaging area for absorbed power density, the results show a good correlation between the peak absorbed power density averaged over a small area of around one square centimeter and the peak rising temperature.
