Chromatic Aberration in Metalenses
Cristian E. Gutiérrez, Ahmad Sabra
This paper provides a mathematical approach to study chromatic aberration in metalenses. It is shown that radiation of a given wavelength is refracted according to a generalized Sn…
On the existence of dichromatic single element lenses
Cristian E. Gutierrez, Ahmad Sabra
Due to dispersion, light with different wavelengths, or colors, is refracted at different angles. Our purpose is to determine when is it possible to design a lens made of a single…
The planar Least Gradient problem in convex domains
Piotr Rybka, Ahmad Sabra
We study the two dimensional least gradient problem in a convex, but not necessary strictly convex region. We look for solutions in the space of functions satisfying the bound…
Special cases of the planar least gradient problem
Wojciech Górny, Piotr Rybka, Ahmad Sabra
We study two special cases of the planar least gradient problem. In the first one, the boundary conditions are imposed on a part of the strictly convex domain. In the second case,…
