Absorbed power in two antennas located near a human head model

With the rapid proliferation of cellular telephones, there is concern regar ding the detrimental effect of the electromagnetic waves on the human body. As a method to reduce the absorbed power (SAR) in the human body, a cellul ar phone with two antennas is proposed. As the simplest model, two line cur rent sources placed on the two-dimensional cylindrical human head and its n eighborhood are considered. The structure is compared with a single line cu rrent source on the human head. From the numerical results, it is shown tha t the total absorbed power can be reduced by 10% and the peak SAR to one-qu arter. (C) 2000 Scripta Technica, Electron Comm Jpn.
