Simulation Mode
Light entering a negative-index metamaterial bends backward — opposite to every natural material. Snell's Law still applies; the angle just goes the wrong way.
n(normal) = 1.5
n(meta) = −1.0
Materials whose properties come not from chemistry, but from engineered geometry at sub-wavelength scales. You can build structures that bend light backward, block sound completely, or have negative mass density.
