摘要
近场扫描微波显微镜因具有强大的穿透能力和无损检测优势,已成为微纳尺度下表征材料电磁特性的重要工具.本文首先介绍了近场扫描微波显微镜的结构原理、探头仿真优化以及图像倾斜修正方法.然后,阐述了近场扫描微波显微镜测量样品局域高频电导率和介电常量的方法.最后,重点探讨了近场扫描微波显微镜在材料和生物等领域的应用,详细分析了所获取的点扫描图、线扫描图和面扫描图.本文旨在帮助读者更深入地了解近场扫描微波显微镜的现状及其未来应用前景.
Abstract
Near-field scanning microwave microscopy(NSMM)has emerged as a crucial tool for characterizing electromagnetic properties at the micro and nanoscale for its strong penetration capabili-ty and non-destructive detection.This article firstly introduced structural principle of NSMM,probe simulation optimization,and methods for correcting image tilt.Then,the article elaborated on the measurement of local high-frequency electrical conductivity and permittivity of samples.Finally,the application of NSMM in the fields of materials and biology was discussed especially,and the obtained point scan,line scan and plane scan were analyzed in detail.This article aimed to enhance readers'un-derstanding of the current status and future prospects of NSMM.
