The diagram below shows a water wave reflected at a plane ... 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 ...

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 ...

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 ...
