Abstract
The subject of this article is my personal path from the near-field optical (NFO) microscope to the optical antenna and its potential for modern optics.
Highlights
One day in 1998, when walking through my city, I watched the TV antennas on the roofs of the houses
After invention [1] of the near-field optical (NFO) microscope, the first microscope that broke the diffraction limit [2], I had been searching for the optimum shape of a NFO probe
In 1999 I had to give a talk at the Second Asia-Pacific Workshop on Near Field Optics in Beijing
Summary
One day in 1998, when walking through my city, I watched the TV antennas on the roofs of the houses. I saw how the electrons were swapping back and forth in the antenna rods, how the gap hindered their motion and how, in response, a large electric field built up in the gap. This gap was arbitrarily small compared to the length of the antenna. Since the latter is roughly half a wavelength, the field in the gap is a typical, no: the archetypical nearfield!
