Abstract

In this paper, we compared the spatial peak SAR values measured with and without holding the hand-held phones to check the present recommended spatial peak SAR. To better understand the analysis of the SAR effect values, SAR is measured with hand phantoms, made and recommended for the use of Bar-type and Folder-type hand-held phones. The measured results have shown that use of the hand considerably reduces the spatial peak SAR value in a head phantom. We compared the spatial peak SAR values measured with and without accessories. To better understand the analysis of the effects of SAR values with accessories, SAR is measured with accessories composed of three kinds of earrings and glasses. The measured results proved in study that the spatial peak SAR value in a head phantom is not affected by the earrings but by the glasses. The glasses considerably increases the spatial peak SAR value in a head phantom while using Bar-type phones, although the effects are modest with Folder-type phones.

본 논문에서는 현재 권고되고 있는 측정방법이 최대 SAR를 측정할 수 있는 조건인지를 판단하기 위하여 손으로 휴대폰을 잡고 있을 때와 손을 사용하지 않았을 때 및 액세서리 사용 여부에 따른 국부 SAR(Specific Absorption Rate)를 비교 분석하였다. 손의 영향을 측정하기 위하여 바(Bar)형과 폴더(Folder)형 휴대폰을 잡는 형태에 따라 2가지 손 팬텀을 제작하였으며, 액세서리의 영향을 측정하기 위하여 각각 3가지 형태의 귀걸이와 안경을 사용하였다. 분석 결과, 손의 영향으로 인하여 머리의 국부 SAR 값이 상당히 감소하였다. 귀걸이에 의한 영향은 없었으며, 안경을 사용할 경우 바형 휴대폰에서는 머리의 국부 SAR 값을 상당히 증가시키고 있으나 폴더형 휴대폰에서는 영향이 없는 것으로 나타났다.
