When Refraction AI was founded in 2019, its goal was to use robotics to bring down the cost of last-mile delivery. Over the past couple of years, the startup has worked directly with restaurants in ...

Figure 1: Diagram and SEM image of fabricated fishnet structure. Here we experimentally demonstrate the first 3D optical NIM by directly measuring the angle of refraction from a prism made of cascaded ...

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 ...

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 ...

There are different ways to investigate refraction in rectangular blocks. In this required practical activity, it is important to: make, measure and record the angles of incidence accurately using a ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

ABSTRACT Recent advances have made ground‐based relative astrometry accurate to 100 microarcseconds (μas) or better a possibility. An important systematic effect on such measurements is the refraction ...

Luke Schneider will be Ann Arbor-based Refraction AI's new CEO. Image courtesy of Refraction AI. (Refraction AI Inc.) ANN ARBOR, Mich. – Mobility industry veteran Luke Schneider has been named as the ...

When a wave or light ray moves from one medium to another its speed changes. The direction of the ray may also change. This property of waves is called refraction and commonly occurs with light rays.
