摘要

针对多频点、大样本量生物电磁暴露系统中剂量差异特征不明确的问题，采用生物电磁仿真软件Sim4Life建立了4种对比仿真环境，仿真频率点为1.8 GHz、2.4 GHz、3.6 GHz和5.8 GHz，对实验小鼠的散射电场和全身平均比吸收率（Whole body average specific absorption ratio，WBASAR）进行了仿真计算及分析。结果表明：受到电磁散射的影响，邻近布局中实验动物的WBASAR值随空间分布变化，变化规律与激励电场的分布趋势相似；激励电场是引起WBASAR值变化的主要因素。此外，WBASAR值的变化还受到频率的影响，高“身体尺寸-波长”比值抑制WBASAR值的变化。针对实验动物的电磁剂量变化特征，提出了降低群体剂量不确定性的设计建议。本研究为生物电磁实验平台的设计提供了剂量评估基础。

Abstract

In this study, the issues of unclear characteristics of dose differences in multi-frequency and large-sample bioelectromagnetic exposure systems were studied. For this, four contrast simulation environments were established using Sim4Life. The frequency points in the simulation were set to 1.8, 2.4, 3.6, and 5.8 GHz, respectively. The scattering field and whole-body average specific absorption rate (WBASAR) values were simulated and analyzed. The results revealed that the WBASAR value for experimental animals was influenced by the electromagnetic scattering of adjacent animals, and the spatial distribution of the WBASAR value was similar to the trend followed by the excitation field distribution. The excitation field was the primary factor causing the variation in the WBASAR distribution. In addition, the WBASAR distribution varies with frequency, and a higher ratio of body size to wavelength inhibits the WBASAR variation. Furthermore, a design suggestion for the exposed platform was proposed to reduce group dose uncertainty based on the variation characteristics. Overall, this study provides a dose evaluation basis for the design of electromagnetic exposure systems.
