##Aircraft can safely traverse the beam and tests have demonstrated that even the sensitive honeybee is unaffected,
Semiconductor lasers typically emit into elliptical beams that are really hard to work with and the new metasurface optical components could replace expensive optical systems used to circularize the beams.
The small size of these devices would also allow for more compact systems. The team is currently working with industrial partners to create metasurfaces for use in commercial devices such as miniature cameras and spectrometers,
which uses muon beams acting as magnetic probes to reveal magnetic properties on a nanoscale.
To obtain the high-resolution hologram, an atomically sharp, tungsten tip acts as a source of a divergent beam of highly coherent electrons.
When the beam hits the sample, part of the beam is scattered and the other part is affected not.
a pattern resulting from the interference of the two beams.""This is the first time to directly observe the helical structure of the unstained tobacco mosaic virus at a single-particle level,
It converts solar rays into microwaves--using conventional photovoltaic solar panels--and then beams the microwave's energy to microwave collector farms at designated locations On earth.
and a different image when illuminated by a vertically polarized beam.""The two images will appear overlapped under illumination with light polarized at 45 degrees,
In another experiment, the team was able to use a metasurface to create a beam with radial polarization, that is, a beam
whose polarization is pointing toward the beam axis. Such beams have shaped doughnut intensity profiles and have applications in superresolution microscopy, laser cutting, and particle acceleration."
and generate these beams with higher efficiency and more purity.""The team is currently working with industrial partners to create metasurfaces for use in commercial devices such as miniature cameras and spectrometers,
giving rise to a brilliant kev X-ray emission. his so-called betatron radiation is emitted in a collimated beam with excellent spatial coherence and remarkable spectral stability.
supplies beams from exotic elementary particles called muons, which can be used to study nanomagnetic properties. The project took place in collaboration with a research group headed by Stephen Lee from the University of St andrews, Scotland n

Shining a light pulse on to the cavity excited the dye atoms into emitting light in a tightly focused beam.
such powers could only be achieved by combining the optical beams from at least four single bars l
