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 ...

At a specific angle of incidence, the refraction angle reaches 90°, which is the maximum refraction angle possible. At this particular point, known as the critical angle, the light beam travels ...

A light ray is traveling in a transparent material of refractive index 1.51 at an angle of incidence of 38 degrees and approaches a second material of refractive index 1.46. Solve for (a) the angle of ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...
