Quite unexpectedly, THz and infraredspectroscopy has now a real chance to solveproblems in the nanosciences. This rests ona new microscope technique that overcomesthe Abbe diffraction limit, by using thenear field of a metal antenna in closeproximity to a scanned sample surface. HereI briefly summarize present activities inthe microwave, mid-infrared and visiblespectral ranges. It seems straightforwardand highly desirable to fill the existinggap between about 20 GHz and 20 THz, andattain spatial resolution of 10 nm andbelow also in this important part of theelectromagnetic spectrum.
非常出乎意料的是，太赫兹和红外光谱学现在真的有机会解决纳米科学中的问题。这基于一种新的显微镜技术，该技术通过使用靠近扫描样品表面的金属天线的近场来克服阿贝衍射极限。在此，我简要总结一下微波、中红外和可见光谱范围内的当前研究活动。填补大约20吉赫兹至20太赫兹之间的现有空白，并在电磁频谱的这一重要部分也实现10纳米及以下的空间分辨率，似乎是直接且非常可取的。
