🧪 Metamaterial Negative Refraction (2D)

Interactive 2D ray-and-wavefront simulation of negative refraction in an electromagnetic metamaterial. Adjust incidence angle, frequency and effective index to see the transmitted ray bend to the same side of the normal as the incident ray, with phase fronts visibly propagating backward while energy still flows forward.
