Abstract

Terahertz (THz) electromagnetic waves, known for their unique response to water, offer promising opportunities for next-generation biomedical diagnostics and novel cancer therapy technologies. This study investigated the impedance-matching effect, which enhances the efficiency of THz wave delivery into tissues and compensates for the signal distortion induced by the refractive index mismatch between the target and the sample substrate. Three candidate biocompatible materials, water, glycerol, and petroleum jelly were applied to a skin phantom and compared using THz two-dimensional imaging and time-of-flight imaging methods. Finally, we successfully demonstrated impedance-matching effect on mouse skin tissues.

摘要

太赫兹（THz）电磁波以其对水的独特响应而闻名，为下一代生物医学诊断和新型癌症治疗技术提供了广阔的前景。本研究调查了阻抗匹配效应，该效应可提高太赫兹波传输到组织中的效率，并补偿由目标与样品基质之间的折射率失配引起的信号失真。将三种候选生物相容性材料，即水、甘油和凡士林应用于皮肤模型，并使用太赫兹二维成像和飞行时间成像方法进行比较。最后，我们成功地在小鼠皮肤组织上证明了阻抗匹配效应。
