Flat lenses, such as metalenses, exist, but they come with hefty price tags and a high degree of complexity, and only a small number of devices are available. In the race to increase the quality ...
A team with researchers at the University of Tokyo and JSR Corp. fabricated and tested flat lenses called Fresnel zone plates (FZPs), but did so for the first time using only common semiconductor ...
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 ...
