다양한 전자기(EM)파 응용이 일반화되었으며 인간은 전자기파에 자주 노출됩니다. 따라서 전자파가 인체에 미치는 영향을 평가해야 합니다. 본 연구에서는 스마트폰에서 방출되는 전자기파에 의한 전자파 인체흡수율(SAR)에 주목하여 고해상도 수치 스마트폰 모델을 개발하고, 위치와 기울기 각도(디스플레이 사이의 각도)를 변경하여 SAR 변화를 연구했습니다. 스마트폰 모델 및 수평면)의 스마트폰 모델은 인간의 복부를 기준으로 하며, 복부 앞에서 다양한 기울기 각도로 스마트폰을 사용한다고 가정합니다. 계산 결과에 따르면 인간 모델의 표면 모양이 SAR 변화에 영향을 미치는 것으로 나타났습니다.

Abstract: Various electromagnetic (EM) wave applications have become commonplace, and humans are frequently exposed to EM waves. Therefore, the effect of EM waves on the human body should be evaluated. In this study, we focused on the specific absorption rate (SAR) due to the EM waves emitted from smartphones, developed high-resolution numerical smartphone models, and studied the SAR variation by changing the position and tilt angle (the angle between the display of the smartphone model and horizontal plane) of the smartphone models vis-à-vis the human abdomen, assuming the use of the smartphone at various tilt angles in front of the abdomen. The calculations showed that the surface shape of the human model influenced the SAR variation.
