Volumetric integrated optical micro- and nanosystems are becoming the new frontier in photonics. Fine control over the material structure within a volume enables novel physical phenomena and ...

THE increasing application to various radio purposes of ultra-short electric waves of less than 10 m. in wave-length has given a new stimulus to the problem of calculating the field strength at ...

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 ...

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 ...

Google Earth provides a cornucopia of exotic images of our planet taken from above. For the most part, the focus of attention is on the land and the cities, roads and natural formations that it ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...
