... of Engineering and Applied Sciences (SEAS) have demonstrated experimentally and theoretically that the surface plasmon resonances of metal nanoparticles in a periodic array can have considerably ...
... created by the spinning to help keep the two surfaces a mere 20 nanometers apart.
Air ... system described by the UC Berkeley engineers uses surface plasmons that have much shorter wavelengths than light ...
... first time that metallic microcavities based on surface plasmons can have a large quality factor and can thereby ... yet another quasi-particle called a surface plasmon polariton(SPP). Such polaritons play ...
... again later. When the molecule moves, it changes the surface plasmon resonance in that tiny area of the metal ... recent issue of Nano Letters.
In essence, plasmonic devices would allow computers to get ...
... chemicals, but in order to test for more than one chemical today, manufacturers have to use more than one sensor."
Surface plasmon resonance devices currently have a wide range of applications. They ...
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if ...
... to stay inside a space that small, Oulton said.
They have squished light beyond these limits using surface plasmonics, where light binds to electrons allowing it to propagate along the surface of ...
... the theory of relativity, they are fascinating objects and can be utilized in optical communications.
The surface plasmon pulses discovered at Penn belong to the same class of superluminal wave ...
... these problems. The key to this new research is the creation of a tiny electrical disturbance called a "surface plasmon." When light strikes a piece of metal it can set up waves in the surface of the ...

The researchers, however, have overcome this hurdle by using not photons but surface plasmons, which enabled them to create a resonator 44 nanometers in diameter, or ...
... it could someday form the foundation
of circuits made of light, not electrical impulses.
The spaser (surface plasmon laser) uses excited gold
nanoparticles to produce a laser with a wavelength ten ...
... utilize these tiny optical excitations. However, the resistance inherent in metals causes these surface plasmons to dissipate almost immediately after being generated, posing a critical challenge to ...
... cages, absorbed by them, or a combination of these two processes.
Just as they can tune the surface plasmon resonance, the scientists can adjust how much energy is absorbed rather than scattered by ...
