Meta-optics employ sub-wavelength nanostructures (scatterers) arranged across a surface to manipulate electromagnetic waves and shape the wavefront in ways previously unattainable with traditional ...

This paper covers a discussion of the Abbe Sine Condition and its implication for Flat Optics, including the effects of stop shift and substrate curvature. Following that, we apply Sweatt’s high index ...

This Collection welcomes original research articles on flat optics, with a focus on the design, fabrication, and characterisation of planar optical elements. It also highlights emerging applications ...

To control light, curved lenses are used today, that are often made of glass that is either concave or convex, which refracts the light in different ways. These types of lenses can be found in ...

The MarketWatch News Department was not involved in the creation of this content. A line of high purity calcined alumina optics polishing abrasives offered in seven particle sizes that are ...

A research team at POSTECH, led by Professor Junsuk Rho, along with M.S./Ph.D. students Seokwoo Kim, Joohoon Kim, Kyungtae Kim, and Minsu Jeong, has developed a multidimensional sampling theory to ...

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...
