| Outline of Final Research Achievements |
In this study, we have investigated numerically in detail electromagnetic wave absorption and electromagnetic field strength in a pregnant woman and an adult head by considering the frequency dependency of all tissues in human body, while it is difficult to consider with commercial software. We have analyzed simple sine waves including leak electromagnetic wave from household electrical appliances, and digital modulation waves used for modern telecommunication systems as irradiation waves. The results show that, as the size of the head comes closer to those that may cause an electromagnetic resonance at a certain frequency of our interest, the energy absorption increases, and that the intensity of the electromagnetic field is more intense for steeper transition of digital signals. These results are expected to provide data that are useful for the construction of future telecommunication systems.
