Scientists have long sought to control light in ways that appear to defy the laws of Nature. Negative refraction -- a phenomenon where light bends in the opposite direction to its usual behaviour ...

The refraction makes the apparent vertical movement of the star slow, but it’s still moving to the left. The result is that the star appears to move mostly left, causing the sideways jiggle.

Light Propagation with Phase Discontinuities: Generalized Laws of Reflection and Refraction. Science, 1 September 2011 DOI: 10.1126/science.1210713 ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent ...

Negative refraction, however, is a counterintuitive effect where light in a medium bends in the opposite direction to what is typically observed in nature, challenging conventional understanding ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction ...

The unusual phenomenon of negative refraction of light is central to the realization of interesting optical devices such as superlenses and other novel schemes for guiding and imaging light ...

Atmospheric conditions in the area that night were ripe for super refraction, Maltin found. This extraordinary bending of light causes miraging, which, he discovered, was recorded by several ships ...
