Materials with a negative refractive index — which bend light in the opposite direction to ordinary substances — have sparked huge interest because they can be used to manipulate the flow of ...

Well, OK, not exactly. A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air ...

GRAND RAPIDS — Every day we see and use light for numerous daily functions, but did you know you can actually bend light? Its called refraction and our experiment today is going to show you how its ...

Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons. Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending ...

Scientists have unveiled a groundbreaking discovery: a material capable of bending light in unprecedented ways. This advancement opens up possibilities for innovations in optics, including superlenses ...

Guy Bartal, from the light refraction lab at Berkeley, talks with Scott Simon about the research they're doing on "invisible cloaks." Bartal overseas research in this lab, and is a co-author of two ...
