Metamaterials Enable Time Reflection of Electromagnetic Waves
NEW YORK, March 27, 2023 — The reflected images produced when we look at a mirror are caused by electromagnetic lightwaves bouncing off the mirrored surface and creating the common phenomenon called spatial reflection. Similarly, spatial reflections of sound waves form echoes that carry our words back to us in the same order we spoke them. For over six decades, scientists have hypothesized about the possibility of a different type of wave reflection, known as a temporal or time reflection. In contrast to spatial
Retroreflective Material Could Help Autonomous Vehicles to Read Traffic Signs
BUFFALO, N.Y., Sept. 3, 2021 — Research at the University at Buffalo has explored the science behind microscale concave interfaces (MCI) — structures that reflect light to produce beautiful and potentially useful optical phenomena. In a published paper, Buffalo engineering...
Flexible Film Creates Colors from Reflected Light
ORLANDO, Fla., June 26, 2015 — From couture to camouflage, a new ultrathin color-changing film could one day change what we wear. Unlike other flexible display technology, the film, which was developed at the University of Central Florida, reflects rather than emits light. It was...
MEMS Display Harnesses Ambient Light to Create Color Images
SAN DIEGO, June 23, 2015 — A new type of display that uses tiny mirrors instead of light-emitting pixels could reduce screen glare and the amount of energy used by consumer electronics. Based on microelectromechanical systems (MEMS), the display consists of a thin absorbing...
Magnetic Mirror Reflects Light in New Ways
ALBUQUERQUE, N.M., Oct. 16, 2014 — A new magnetic mirror uses non-metallic metamaterial properties to reflect IR light.
Touch Screens Repel Fluids, Cut Glare and Still Look Good
BARCELONA, Spain, July 17, 2014 — Touch screens with nanostructured surfaces that ward off glare, reflection and fluids could easily be mass-produced, according to researchers from the Institute of Photonic Sciences. In one study, the researchers demonstrated a highly transparent...
System Pushes Better Light Control
CAMBRIDGE, Mass., March 27, 2014 — More precise control of light could be on the horizon, prompting advances in solar photovoltaics, detectors for telescopes and microscopes, and privacy filters for display screens.
Perfecting Digital Imaging
CAMBRIDGE, Mass., July 25, 2013 — The best software and video cameras lag behind reality, unable to capture images that look exactly the way our eyes expect them to look. But new research in computer graphics could change all that, advancing artificial vision, 3-D displays and video...
Fishy Felon Breaks a Law of Physics
BRISTOL, England, Oct. 23, 2012 — A multilayer crystalline structure used by silvery fish to evade ocean predators bends the laws of physics and could be the key to developing better optical devices.
Plasmonic nanoantennas promise optics with strange new abilities
WEST LAFAYETTE, Ind. – Arrays of plasmonic nanoantennas can abruptly change the phase of light, potentially enabling more powerful microscopes, computers and telecommunications systems. “By abruptly changing the phase, we can dramatically modify how light...
‘Plasmonic Nanoantennas’ Promising for Optics
WEST LAFAYETTE, Ind., Jan. 3, 2012 — Arrays of tiny “plasmonic nanoantennas” have been developed that can precisely manipulate light in new ways, potentially enabling optical innovations such as more powerful microscopes, computers and telecommunications. Researchers...
Portable Microscope Uses Holograms Instead of Lenses
LOS ANGELES, Aug. 31, 2011 — A compact, lightweight, dual-mode microscope that uses holograms instead of lenses could prove to be a boon for global health initiatives. The palm-size device, developed at UCLA, costs only $50 to $100 to make. It features a transmission mode...
Beetle ‘Bling’ Reveals Optical Secrets
SAN PEDRO, Costa Rica, April 27, 2011 — Deep in Costa Rica’s tropical rain forests live two lustrous beetle species that are giving optics researchers new insights into the way biology can recreate the appearance of metals by means of reflected light. Scientists at the University of...
G-S Plastic Optics Expands Metrology Capability
ROCHESTER, N.Y., Nov. 17, 2010 — G-S Plastic Optics has announced an upgraded metrology laboratory with the addition of a PerkinElmer Lambda 950 spectrophotometer. The company’s goal is to improve its core competencies of creating high-precision polymer optics. The...
For better LEDs, two V’s could mean victory
Aug 1, 2010 — For light-emitting diodes, a brighter, more efficient and groovier future may be at hand. The result could be billions of dollars of annual energy savings, say researchers from the National Institute of Advanced Industrial Science and Technology...
My Summer with MIRTHE
Mar 18, 2010 — I have never been particularly interested in the field of engineering. Physics? No thank you, I’ll stick to English and history. So when my father came to me with the opportunity to work in a lab in Princeton for the summer, I was feeling more than...
Stirring Up a Passion for Photonics
SAN FRANCISCO, Jan. 24, 2010 — It rather stands out among the shiny high-tech devices strung along the aisles at the BiOS trade exhibition — a simple pine valise propped open at one of the tables belonging to Om...
New Cloak vs. Cloak Classic
DURHAM, N.C., Jan. 15, 2009 – A new type of device that can render an object invisible in visual light has been revealed by the same research team that constructed the first prototype in 2006. The new device is significantly more sophisticated at cloaking in a broad range of...
The Polarization of Light by Reflection
Dec 11, 2008 — While the majority of the western world uses polarization-based advances in technology on a daily basis few realize that, were it not for the polarizability of light, these technologies would not be possible.
