高灵敏度太赫兹超材料对于生物组织切片的研究
Terahertz metamaterials with high sensitivity for biological tissue slices study
摘要
Abstract
Terahertz(THz)wave has great development potential in biomedical science due to its nonionizing,labelless and real-time characteristics.To distinguish biological tissues with similar permittivity,a metamaterial with Fano resonance is designed and fabricated for THz reflection imaging.The simulation and experimental results show that the reflection sensitivity of the metamaterial is 132 GHz/RIU at 0.82 THz.The metamaterial not only enhances the contrast of imaging resolution plate,but also improves the contrast between the muscle and the fat tissues by approximately 7.5%,therefore,it can improve the contrast of biological tissue slice images.This work has established an experimental and theoretical foundation for future terahertz applications in clinical tissue samples.关键词
