본 연구의 목적은 인간이 흡수하는 전력을 이용한 전신평균전자파흡수율(WB-SAR) 추정 방법을 확립하는 것이다. 원통형 외부 필드 스캐닝 기술은 방사된 RF(무선 주파수) 전력을 측정하는 데 사용됩니다. 이 기술은 자세나 크기가 다른 사람의 노출 선량 측정을 단순화하는 것을 목표로 채택되었습니다. 본 논문에서는 제안된 측정 방법을 검증하기 위해 수치적 인간 팬텀 모델과 원통형 스캐닝 조건을 사용하여 FDTD 분석을 수행했습니다. 우리는 UHF 원거리장 노출 조건에 대한 실험적인 WB-SAR 측정 시스템을 개발하기 위해 유전체 렌즈를 사용하여 테스트된 인간 팬텀의 평면파 조사를 달성하는 방사선 시스템을 설계합니다. 또한 간단한 기하학적 모의체의 흡수 전력 추정을 확인하고 측정 시스템의 측정 오류를 추정하기 위해 구축된 SAR 측정 시스템을 사용합니다. 마지막으로 남성 성인 및 아동 인간 팬텀 모델에 대한 WB-SAR의 측정 결과를 논의합니다.

Abstract: The purpose of this study is to establish a whole-body averaged specific absorption rate (WB-SAR) estimation method using the power absorbed by humans; a cylindrical-external field scanning technique is used to measure the radiated RF (radio-frequency) power. This technique is adopted with the goal of simplifying the estimation of the exposure dosimetry of humans who have different postures and/or sizes. In this paper, to validate the proposed measurement method, we subject numerical human phantom models and cylindrical scanning conditions to FDTD analysis. We design a radiation system that uses a dielectric lens to achieve plane-wave irradiation of tested human phantoms in order to develop an experimental WB-SAR measurement system for UHF far-field exposure condition. In addition, we use a constructed SAR measurement system to confirm absorbed power estimations of simple geometrical phantoms and so estimate measurement error of the measurement system. Finally, we discuss the measurement results of WB-SARs for male adult and child human phantom models.
