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 ...

A ray diagram showing refraction at the boundary between air and glass Refraction can cause optical illusions as the light waves appear to come from a different position to their actual source. The ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. is the ...
