摘要
考虑人体电特性的建模是对人体进行电磁生物效应研究的基础,提出了一个可以用于计算人体输入阻抗的新的人体电路模型;基于该电路模型给出了在人体圆柱模型下的输入阻抗计算方法.并用试验证明,据此计算出来的人体阻抗会随曝露系统的维数增加而减小,反映出功率吸收的现实.应用该模型分析人体阻抗变化,可有益于人体健康状态信息的获取,为进行医学诊断提供帮助.
Electric model of human body impedance is essential for research on bio-electromagneric effect but previous models are too theoretical to describe reliably real human body. We hence propose a new human body circuit and give a cylindrical model for impedance calculation of human body, describing algorithm based on the cylindrical human body model and providing confirmarion experiment result that human body impedance reduces with dimension increase of transverse electromagnetic （TEM） cell, showing real variation of absorption power by human body. The algorithm may be applied to variation analysis of equivalent human body electric impedance, which can reflect health or sick state of human body and may provide a possible approach to diseases dialog for httrnan body.
