چکیده

The commercial wireless terminal is usually hold in the vicinity of a human body, it is needed an attention for the specific absorption rate (SAR) in an abdomen. In addition, the electromagnetic (EM) waves from the wireless terminal penetrate a deep region of body, because the wavelength of the EM waves of the wireless terminal operating in VHF band is longer than those of a cellular phone operating in the GHz band. In this paper, to evaluate the SARs of a male and a female when they are wearing a wireless terminal on their abdomens, we calculated the SAR in the abdomen using the numerical human model exposed to EM waves from several positions of a normal mode helical antenna (NHA) with a metallic case.

SAR Calculation in a Fetus Exposed to EM Wave from a Wireless Radio Terminal Close to the Abdomen of a Pregnant Woman

In the past few years, radio frequency (RF) devices, which are usually used in the vicinity of a human body, are increasing. The health effects of the electromagnetic (EM) waves from RF devices on the human body are dependent on the frequency and strength of the waves. The absorbed RF EM energy mainly contributes to tissue heating. The specific absorption rate (SAR) has been used as the standar...
