Absorbed power in two antennas located near a human head

摘要

With the rapid proliferation of cellular telephones, there is concern regarding 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 cellular phone with two antennas is proposed. As the sim- plest model, two line current sources placed on the two-di- mensional cylindrical human head and its neighborhood are considered. The structure is compared with a single line current source on the human head. From the numerical results, it is shown that the total absorbed power can be reduced by 10/100 and the peak SAR to one-quarter.
