摘要： 生物组织的介电特性是组织在电磁场中吸收和耦合电磁能的特性表征，是组织对外加电磁场响应特性的基础，无论对生物理论研究还是医学应用都具有非常重要的意义。太赫兹波对生物组织基本没有伤害，并且具有较好的穿透能力。当太赫兹射线用于监测生物组织、分析其结构和组成时，可以克服常用的可见光或紫外光对生物组织进行分析时信号弱、图像模糊等问题。太赫兹频段生物组织介电特性的研究具有重要医学应用价值，但很多生物组织在太赫兹波段的介电特性是未知的。

Abstract： The dielectric properties of biological tissue is the characterization of tissue uptake in the electromagnetic field and electromagnetic coupling, is the basis for the organization to external electromagnetic field response characteristics of both the theoretical biology research and application in medicine has very important significance. Terahertz wave has no harm to biological tissue, and has better penetration ability. When THz radiation is used to monitor biological tissue, analyze its structure and composition, it can overcome the problems of weak signal and fuzzy image in the analysis of biological tissue by visible light or ultraviolet light. It is of great importance to study the dielectric properties of biological tissues in the terahertz frequency band, but the dielectric properties of many biological tissues in the terahertz wave band are unknown..
Keywords： biological；dielectric response；terahertz wave
