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 ...

The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It arises due to the wave nature ...
