This paper describes a method for computing atmospheric refraction that is simple, highly accurate, and usable for wavelengths λλ3000-10,000 Å. When compared with the Refraction Tables of the Pulkovo ...

Figure 1: Analytical study of one-dimensional chains of resonant point scatterers. Starting from this unit cell that creates the single negative property, we build two new configurations just by ...

A refraction test is usually given as part of a routine eye examination. It may also be called a vision test. This test tells your eye doctor exactly what prescription you need in your glasses or ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions bend.
