X-ray diffraction, reflectivity, standing waves and evanescent waves will be discussed in a context that leads to an understanding of how these x-ray methods are presently being used at synchrotrons ...

The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...

The goal of the current project is to open a new field of research by realizing the first diffraction experiments of atomic matter waves through crystalline 2D membranes like graphene. Such ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

We have recently succeeded in detecting the diffraction pattern of radio waves scattered from the electron trail as a meteor passes at right angles through the aerial beam. These observations lead ...
