| Abstract(in English) | Recently, practical use of wireless communication technologies using quasi-millimeter wave and millimeter wave bands, such as 5G system, has been expected. Expansion of the technologies using the new frequencies will increase the public concern of exposure to electromagnetic fields. An absorbed power density is used as a metric of the basic restriction at frequencies above 6 GHz in the ICNIRP guideline of human exposure to electromagnetic fields. From these backgrounds, we aim to develop measurement method of absorbed power density at frequencies over 6 GHz. In this study, an estimation method of the absorbed power density using an inverse problem method was proposed. An applicability of the method was assessed using the computational simulation at 28 GHz. |
