Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 250, No. 1263 (Apr. 7, 1959), pp. 439-459 (21 pages) An intricate repetitive fringe pattern, due to the ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

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 ...
