Metasurface optical antireflection coating [PDF]

open access: yesApplied Physics Letters, 2014
Light reflection at the boundary of two different media is one of the fundamental phenomena in optics, and reduction of reflection is highly desirable in many optical systems. Traditionally, optical antireflection has been accomplished using single- or multiple-layer dielectric films and graded index surface structures in various wavelength ranges ...

Antireflective Boundary Conditions for Deblurring Problems [PDF]

open access: yesJournal of Electrical and Computer Engineering, 2010
This survey paper deals with the use of antireflective boundary conditions for deblurring problems where the issues that we consider are the precision of the reconstruction when the noise is not present, the linear algebra related to these boundary conditions, the iterative and noniterative regularization solvers when the noise is considered, both from
