皮肤基底癌组织太赫兹频段时域模型表征

Time-Domain Modeling of Skin Basal Carcinoma Tissue in Terahertz Band

本文基于双德拜模型,提取了皮肤基底组织在太赫兹频段的时域电磁参数。通过分析,本文获得了皮肤基底癌组织在0.1THz下的时域电磁参数(σ=105.0453S/m,εr=4.1648)。与正常皮肤组织在0.1THz下时域电磁参数(σ=92.9609S/m,εr=4.0825)对比可知,癌症组织对太赫兹波能量的吸收效果明显高于正常皮肤组织。这一研究结论为进一步探索皮肤基底癌组织在太赫兹频段的探测技术提供部分依据。

In this paper,based on the double Debye model,time-domain electromagnetic parameters of skin basal carcinoma tissue in terahertz band is extracted.Through analysis,time-domain electromagnetic parameters of skin basal carcinoma tissueat 0.1 THz is obtained in this paper(σ=105.0453 S/m,εr=4.1648).Comparedwith time-domain electromagnetic parameters of normal skin tissue at 0.1 THz(σ=92.9609 S/m,εr=4.0825),the absorption effect of the cancer tissue on the THz wave energy was significantly higher than that of the normal skin tissue.This study provides some evidence for the further exploration of the detection technology of skin basal carcinoma tissue in the terahertz frequency range.
