Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...

SIAM Journal on Applied Mathematics, Vol. 48, No. 1 (Feb., 1988), pp. 1-37 (37 pages) We derive an asymptotic partial differential equation which describes the diffraction of a weakly nonlinear high ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 209, No. 1096 (Oct. 8, 1951), pp. 81-96 (16 pages) The radio waves from 'radio stars' may suffer ...

[The Action Lab] had a very serious technical problem. His daughter wanted to 3D print sparkly unicorns. But how do you make a 3D print sparkly? Turns out, he had used a diffraction grating before to ...

The first laboratory-based diffraction contrast tomography (DCT) system for 3D grain imaging was launched by Carl Zeiss X-ray Microscopy, a pioneer in bringing synchrotron imaging capabilities to the ...

Optical computing could benefit from the recent development of a novel electromagnetic wave. An unusual wave that does not spread out as it travels could become a key component in speedy computer ...

For pharmaceuticals, knowing the chemical composition is not enough - molecular geometry and crystal structure also play an important role in a drug's activity. By using a method based on electron ...
