Optical microscopy has revolutionized many fields such as microelectronics, biology and medicine. However, the resolution of a conventional optical lens system is always limited by diffraction to ...

The study of electromagnetic diffraction and scattering in metamaterials encompasses how artificially structured materials manipulate wave propagation at scales comparable to or smaller than the ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
