(Nanowerk News) To design and improve energy storage materials, smart devices, and many more technologies, researchers need to understand their hidden structure and chemistry. Advanced research ...

US engineers have succeeded in creating a near-perfect ‘superlens’ that uses the principles of metamaterials to overcome conventional diffraction limits. The lenses could be used in ...

Implementation of the angular spectrum method in Python to simulate diffraction patterns with arbitrary apertures. These examples correspond to the simulations with ...

We consider diffraction by pixelated lenses when the lens size is significantly smaller than the diffraction pattern of single pixels. In that case, the diffraction orders show shapes that have not ...

This paper presents a new design of a planar solar concentrator with spectral splitting of light for space applications. This concentrator spectrally splits the incident light into mainly two parts.

Abstract: Diffractive lens can realize high-resolution imaging with large aperture and light weight. Conventional amplitude-tpye diffractive lens has extremely low diffraction efficiency, and ...

Flat lenses offer a way to minimize the optical aberrations and astigmatisms that conventional spherical lenses can be prone to, and can potentially open up new applications that traditional lens are ...

Researchers have developed a new and improved version of electron diffraction that offers advanced and unique experimental instrumentation for studying particle acceleration to researchers from all ...

With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the ...
