NASA Piggybacks Spectrograph On Comm Satellite To Study Ionosphere’s RF Disruption
The National Aeronautics and Space Administration (NASA) is set to launch its Global-scale Observations of the Limb and Disk (GOLD) mission to study Earth's near-space environment and better understand what disrupts radio signals and satellites used for communications and the Global Positioning System (GPS) for radio navigation.
Harvard-Produced Metalens Is “Next Big Step” In Optics, Virtual Reality
Scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have built the first single lens that can focus the entire visible spectrum of light. The breakthrough means bulky stacked lenses could soon be replaced with simpler, flat metalenses — without loss of resolution.
Rice Scientists Find New Kind Of Quantum Material: The Weyl-Kondo Semimetal
Scientists at Rice University and the Vienna University of Technology in Austria, who have been researching high-temperature superconductivity, have stumbled across a new type of quantum material they call a “Weyl-Kondo semimetal.” It exhibits theoretical properties found in disparate materials, such as topological insulators, heavy fermion metals, and high-temperature superconductors.
Hollow Optical Antennas For Superior Photon Creation And Control
Scientists at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, have introduced a novel plasmonic cavity antenna design that enhances the creation and control of photons emitted by atoms and molecules.
Researchers Finally Prove Existence Of Excitonium, A New Form Of Matter
Scientists using a newly developed spectroscopic technique have finally proven the existence of excitonium, a new form of matter first theorized almost half a century ago.
Ultraviolet Microscope To Dramatically Speed Up Lab Tests
A microscope using ultraviolet (UV) light to provide high-resolution histological images promises to significantly shorten the amount of time diagnostic tests are processed.
U.S. Air Force Aims To Deploy Laser-Armed Fighter Jets By 2021
The United States Air Force Research Laboratory (AFRL), through its Self-protect High Energy Laser Demonstrator (SHiELD) program, has awarded Lockheed Martin a $26.3 million contract to design, develop and produce a high-power fiber laser mounted on a tactical fighter jet by 2021.
Princeton, Penn State Researchers Create Diode Laser From Hybrid Perovskite Material
Scientists at Pennsylvania State University and Princeton University have created a diode laser from hybrid organic-inorganic perovskites – materials that have garnered attention due to their light emitting properties, useful in optoelectronic devices and solar cells.
Ultrafast Pulses Modulate Circadian Rhythm And Blues
Manipulating the spectral components of ultrafast, near-infrared pulses of light can influence neural activity, paving the way for more effective treatments of mood and circadian rhythm sleep disorders, according to a team of researchers at the University of Illinois.
Israeli Researchers Successfully Hide Optical Chip Under ‘Cloak Of Invisibility’
Scientists at Ben-Gurion University of the Negev (BGU) are proposing a new method to obscure an optical chip by bending light around the object. This could be achieved by manipulating waves in the near field region (such as surface plasmons) of a metamaterial surface (a metasurface) on an integrated photonic structure.
