Have you ever wondered how optical nearfields really look like inside of  narrow, sub-wavelength-wide optical nanostructures?  Do they look as expected, or do minor  structure deviations lead to a quite different picture? Here is a method that allows imaging of some special kind of nearfields with the help of swift electrons – a neat collaboration  between our  friends around Professor Ido Kaminer at the Technion and our group. The paper  can be found here.
