In this paper, the electromagnetic interaction between human skin and terahertz radiation is investigated through the double Debye parameters' extraction algorithm. The changes of skin content are contrasted at the frequencies below one terahertz(THz) but the recent approaches could provide only a rough estimation. We propose an global optimization based identification, which results in globally accurate estimators in the frequency range up to two THz, and thus supports the validity of Debye model for Terahertz wave's propagation and reflection in skin. Simulation results confirm our prominent methodology.
本文通过双德拜参数提取算法研究了人体皮肤与太赫兹辐射之间的电磁相互作用。在低于1太赫兹（THz）的频率下对比了皮肤成分的变化，但最近的方法只能提供粗略估计。我们提出了一种基于全局优化的识别方法，该方法在高达2太赫兹的频率范围内能得到全局精确的估计值，从而支持德拜模型对太赫兹波在皮肤中传播和反射的有效性。仿真结果证实了我们卓越的方法。
