European researchers say their study of self-sustaining solitary light wave packets could result in a new generation of computers and optical telecommunications networks. Using light rather than ...
... the physical features on the surface of the structure.
The structure arrests the progress of light waves at multiple locations on the surface and at different frequencies. Previous researchers, Gan ...
Researchers have developed a graded grating structure that can be scaled to dimensions compatible with light waves in both the terahertz and telecommunications portion of the spectrum. The achievement ...
... 1950 created a theoretical model for the way in which light passes through small holes. For instance, ... exits the hole and subsequently how the light waves move outwards in the same way as ring-shaped ...
... may strike a glancing blow off the surface of an asteroid, producing gamma rays (short wavelength light waves). Researchers now report that they can use this gamma ray radiation to ...
... a rising MCG School of Dentistry junior. "The light waves produce free radicals that activate ... percent increase in cell suicide, or apoptosis, in the light-treated tumors. The frozen protein extracts ...
... Optics researchers succeeded previously in passing light through gaps 200 nanometers wide ... wire, as the wire approaches the metal sheet, light waves are trapped in the gap between them, the researchers ...
... Science. "The magnetic field, which oscillates at a perpendicular angle to the electrical field in a light wave, is essentially blind to the upright nanowires, a feature which significantly reduces ...
... along which light can propagate. This is only possible if the light meets strict preconditions so that the scattered light waves can reinforce one another on the way to the exit.

... Rice by nanophotonics pioneer Naomi Halas. Nanoshells are about 20 times smaller than a red blood cell, and they can amplify light waves and focus them so tightly that scientists can ...
An implant which works by firing infrared light into the inner ear is being investigated by US researchers.
... PWS quantifies the statistical properties of cell nanoscale architecture by using the signal generated by light waves striking the cell.
PWS can provide information not only about individual cells, ...
... Ropers, and Bahram Jalali are putting rogue light waves to work in order to produce brighter ... incandescent bulb in a lamp, it shines with a white light that spans an extremely broad spectrum. But unlike ...
... due to refraction, or the change in speed and thus direction of light waves as they move from air to water.
Wait a minute!? Isn’t the speed of light constant? Yes. But only in a vacuum.
