What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...

Structured Illumination Microscopy (SIM) is a tool which breaks the diffraction resolution barrier to provide resolutions of up to 20nm. The resolution of conventional microscopes is limited by the ...
