If you've been paying attention to the launches of the new generation of game consoles, you've probably heard talk of ray tracing. Ray tracing is a rendering technique for photorealistic graphics by ...

Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its ...

Researchers from North Carolina State University and the University of Texas have developed and demonstrated a new approach for designing photonic devices. The advance allows them to control the ...

In a groundbreaking discovery, physicists have observed light traveling in reverse, an event that significantly challenges our fundamental understanding of physics. This event was noted in certain ...

This is a preview. Log in through your library . Abstract In deep water, when multi-directional random waves symmetric to the direction of propagation are incident obliquely on the shore, directional ...

In a major step toward next-generation electronics, researchers at the University of Minnesota Twin Cities have discovered a way to manipulate the direction of charge flow in ultrathin metallic films ...
