Figure 1: Comparison of positive and negative refraction. We made transmission measurements to confirm our structure's predicted negative refraction, using the interfaces of the photonic crystal in ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...
