(PhysOrg.com) -- When trying to focus sound waves into as small an area as possible, scientists run into a fundamental limit called the diffraction limit. That is, when sound waves are focused into a region smaller than one ...
(PhysOrg.com) -- Conventional lenses can resolve structures around 200 nanometers (nm) in size, but scientists in Europe have for the first time developed a lens capable of achieving optical resolution of under 100 nm at ...
A group of scientists led by researchers from the California Institute of Technology has engineered a type of artificial optical material—a metamaterial—with a particular three-dimensional structure such that light exhibits ...
