Physicists turn to Maxwell’s equations for self-bending light

http://phys.org/news/2012-04-physicists ... nding.html

(Phys.org) -- Can light self-bend into an arc? Can shape-preserving optical beams truly bend along a circular path? A confident answer emerged in this week’s Physical Review Letters. Researchers at Israel’s Technion reported their findings, saying that solutions to Maxwell’s equations suggest it is possible. They have found solutions to Maxwell's equations— the equations governing electromagnetism--that precisely describe initial phases required for truly self-bending light.

Light travels in a straight line; light beams tend to propagate along a straight path. Under forced circumstances—with use of mirrors, lenses, and light guides--light can take a more circuitous path, What has interested some scientists is whether or not light beams can bend themselves along a curved path with no external cause.

What is more, the new report involves wave solutions to Maxwell’s equations that are nondiffracting and capable of following a tighter circular trajectory than was previously thought possible.

The authors said in the report that “We have found nonparaxial accelerating beams and nonparaxial periodically oscillating accelerating beams. These beams are the full vector solutions of Maxwell’s equation for shape-preserving accelerating beams. Moreover, in their scalar form, these beams are the exact solutions for nondispersive accelerating wave packets of the simple and most common wave equation describing time-harmonic waves.”

The study, titled “Nondiffracting Accelerating Wave Packets of Maxwell’s Equations,” by Ido Kaminer, Rivka Bekenstein, Jonathan Nemirovsky, and Mordechai Segev, joins a body of related light-bending research.

Reaching into the research background, ScienceNOW described some study markers, going back to the late 1970s, when physicists at the University of Bristol in the United Kingdom and State University of New York said that an Airy waveform, a wave describing how quantum particles move, can sometimes bend by a small amount. In 2007, physicists at the University of Central Florid generated optical versions of Airy waves by manipulating laser light, and found that the resultant beam curved slightly as it crossed a detector.

The Technion examination is unique in that the scientists claim they figured out how to make light self-bend through any angle, even through a complete circle. (The problem with the Airy function, said study coauthor Mordechai Segev, is that the shape of its oscillations specify the right phases only at small angles.)

Commenting on this week’s findings, Zhigang Chen, a physics professor at San Francisco State University, said in Physics that implications of their work are profound for other linear wave systems in nature, from sound and surface waves in fluids to many kinds of classical waves.”One would expect that the nonparaxial Bessel-like accelerating beams proposed in this study could be readily realized in experiment. Apart from many exciting opportunities for these beams in various applications, such as beams that self-bend around an obstacle one might expect one day light could really travel around a circle by itself, bringing the search for an ‘optical boomerang’ into reality.”

The study authors say that future work should examine the possibility of 3-D accelerating beams, including those with trajectories that do not lie in a single plane. “In practical terms, this work brings accelerating beam optics into the subwavelength regime, through the less-than-wavelength features of our solutions, facilitating higher resolution for particle manipulation.”

This is a new discovery that supports the electric universe, and solutions to Maxwell's equations. In 1861, Maxwell proposed the displacement electric current that fills all of outer space, so that an electric current can travel through an empty space vacuum, but it worked for only a few oscillations, which they said then was light. http://www.phy6.org/Education/wemwaves.html
Light has now been proved to self-bend and self-preserve its original 3D shape by traveling three dimensionally as arcs, around solid objects, even in a vacuum (there's no gravity mass in a vacuum) shows Zhigang Chen. This should destroy the gravity lens interpretation that light bends by gravity passing through dark matter halos around galaxy clusters, and launch a new EU cosmology, that includes all the things that we know here to be true, like how metamaterials mimic all electromagnetic cosmic phenomena. Everything learnt about the universe has come entirely upon electromagnetism. The great blunder was in the 19th century when they decided that outer space was entirely different, and was shaped and formed both by macroscopic gravity and not electromagnetism. Einstein's relativity is Maxwell's equations, with some fictious suppositions like the speed of light c being constant in a vacuum. This we know is not true, because light doesn't travel in a straight line as believed, but travels in arcs or sphere-shaped curved trajectories, even in outer space vacuum, which must distort wrongfully the Hubble redshifts of galaxies, and be warping space and time without gravity by our observations from earth. Magnetohydrodynamics and electrohydrodynamics are accepted by relativity, and are valid electromagnetic equations that have no gravity components. The gravity component they add as an additional space dimension or just to purport their wrong theories.

I thought this was pretty huge myself, thanks for the response.

This isn't an actual "discovery" of fact --- just a conclusion drawn from an extension of Maxwell's equations.
The same assumptions used by JCM apply to the new conclusions... the observation of light is still quite persistently upon rectilinear paths. Now it is true that alleged "diffraction" of the light spectrum does appear to occur at ostensible edges of objects. But the light field about the central line of sight can be understood as a pressure gradient, thus some "pressure vectors" of the light field make it around intervening objects even if the central line of sight is blocked. Looking at a relatively small light source past the edge of a pencil, I see the distant light fringed in red. Optically each portion of the pressure gradient can be traced as a straightline vector to the light field from the eye or photosensitive detector. It is also abundantly evident that the light path "refracts" at "boundaries" between differently dense media, but again it can be demonstrated that this refraction is not a curved path except in the natural or artificial case of the "boundary" condition being a continuum of density shift, as in mirages and such. The "bending" of the light path in these instances leads to natural distortion and blurring of the actual light imaging vectors [rays, beams]. Such is not the case in observed redshifts of distant stars or galaxies. The spectral arrays of astronomical objects are "true images" of their light field, manifesting specific information about the objects' element composition and ionization, temperature, and yes, electrical [current density] state. The spectrum is not [contrary to wave physics demands] a distortion caused by intervening diffraction gratings, lenses, or interference.

The most obvious issue is that Maxwell's equations have absolutely nothing to do with light. Admittedly, such a FACT is of no use when you're looking down the barrel of a black hole firing a quantum superposition of neutrino flavour changing dark inflation field of pure energy.....eye of newt, tongue of toad, stir well till disbelief suspends itself.

The phony gravitational lens interpretation in galaxy cluster RCS2 032727-132623 shows the light of the brightest known background galaxy is warped into nearly a 90 degree arc. Light bends itself into arcs without any gravity requirements. We are seeing larger scaled structures and looking around the corner to see actual 3D shapes of background galaxies, just as the scientist proved in the article.
