本文介绍了一种在太赫兹时域光谱中快速可靠地提取材料参数的新方法，该方法适用于大多数材料，不需要简化假设，也不需要提取不同厚度的样品。给出了一些涵盖所有实际情况的实验示例，特别是，提取过程处理了太赫兹脉冲内反射略有重叠的样本的繁琐情况。
This paper introduces a never method that allows fast and reliable extraction of material parameters in terahertz time-domain spectroscopy, This method could be applied for most of materials and requires neither simplifying assumptions nor samples of different thickness for the extraction, The presented extraction procedure operates either on truncated terahertz signals when temporal windowing is possible, or on full ones otherwise. Some experimental examples covering all practical cases are given, In particular, the extraction procedure treats the tedious case of samples for which internal reflections of the terahertz pulse slightly overlap.
