Among the many potential applications of this nano-sized light source, once the technology is refined, are single cell endoscopy and other forms of subwavelength bio-imaging, integrated circuitry for nanophotonic technology, and new advanced methods of cyber cryptography. ❋ Unknown (2007)
The result is light that is tunable as well as coherent, which fulfills a technological requirement that has posed a major challenge for both photo-imaging and photo-detection in subwavelength optics. ❋ Unknown (2007)
However, whereas the resolution of optical microscopy is limited by diffraction, through subwavelength techniques it becomes possible to visualize features smaller than visible light wavelengths. ❋ Unknown (2007)
This makes them ideal for subwavelength laser and imaging technology.” ❋ Unknown (2007)
So far transformation optics have delivered only hints as to what the future might hold, with a major roadblock being how difficult it is to modify the physical properties of metamaterials at the nano or subwavelength scale, mainly because of the metals. ❋ Unknown (2010)
For this latest work, Zhang and Liu with Zentgraf and Bartal departed from the traditional transformation optics focus on propagation waves and instead focused on the SPPs carried in near-field (subwavelength) region. ❋ Unknown (2010)
Better characterization of single nanoparticles is important to researchers pursuing microscopic optical sensors, subwavelength "super lenses," catalysis and photothermal cancer therapies that use nanoparticles. ❋ PhysOrg Team (2010)
A metamaterial is an electromagnetic medium created by a composite of tiny (very subwavelength) constituent structures, put together in such away that longer wavelengths see an "average" material with properties very different from those of the constituents. ❋ Unknown (2010)
A negative-refractive metamaterial is designed to have an effective "negative" index of refraction, which makes Snell's law (refraction) bend backwards, and can potentially be used for flat-lens near-field imaging, subwavelength imaging (again only in the near field), etcetera. ❋ Unknown (2010)
Increase of group delay and nonlinear effects with hole shape in subwavelength hole arrays ❋ Unknown (2010)
Brongersma's work is based on the unprecedented ability of nanometallic or plasmonic structures to concentrate light into deep-subwavelength volumes. ❋ Unknown (2010)
This time they've demonstrated the first broad-band low-loss imaging with large magnification, where evanescent waves carrying information about subwavelength features are gradually converted into propagating waves. ❋ Unknown (2009)
"We provide a paradigm on the design and use of metamaterials to manipulate sound waves down to subwavelength scales," says co-author Li, a former post doctoral fellow in Zhang's group and now an assistant professor in City University of Hong Kong. ❋ Unknown (2009)
"Our acoustic hyperlens relies on straightforward cutoff-free propagation and achieves deep subwavelength resolution with low loss over a broad frequency bandwidth." ❋ Unknown (2009)
