Three months after the flight of the solar observatory Sunrise – carried aloft by a NASA scientific balloon in early June 2013—scientists from the Max Planck Institute for Solar System Research in Germany have presented ...
(Phys.org) —University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum.
(Phys.org) —Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.
Duke University engineers believe that continued advances in creating ever-more exotic and sophisticated man-made materials will greatly improve their ability to control light at will.
As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer ...
(Phys.org) -- An applied electric voltage can prompt a centimeter-square slice of graphene to change and control the transmission of electromagnetic radiation with wavelengths from the terahertz to the midinfrared.
A new study shows that light transmitted through apertures smaller than the wavelength of light go through a radical change, splitting into two symmetrical counter-rotating polarisations.
(PhysOrg.com) -- Scientists at the University of Glasgow have, for the first time, been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.
A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards.
Microscopes are conventionally used to image tiny features. However, their resolution is inherently limited by the wavelength of light. This limitation means that they can resolve only structures larger than a few hundred ...
