3D Printed Multilayer Structures for High Numerical Aperture Achromatic Metalenses
Cheng-Feng Pan, Hao Wang, Hongtao Wang +8
Flat optics consisting of nanostructures of high-refractive-index materials produce lenses with thin form factors that tend to operate only at specific wavelengths. Recent attempts…
