In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even ...

Even high-performance smart phone cameras still require a stack of lenses that often account for the thickest part of the ...

Abstract: Millimeter-wave (mmWave) communication has emerged as a promising ... To tackle this problem, we propose in this paper a new architecture for mmWave CRAN with advanced lens antenna arrays at ...

Abstract: This paper presents a design of a wideband circularly polarized (CP) metal lens for millimeter-wave applications. The element is designed based on a quadruple-ridged waveguide which can ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Swiss scientists have developed an ultra-thin lens that turns infrared light into visible light using lithium niobate and ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength ...

Researchers from the University of Rochester and University of California, Santa Barbara, engineered a laser device smaller ...
