metacrystal

MET-uh-kris-tuhl

Definition

An engineered material with a periodic structure that does not occur in nature, designed to manipulate quantum states of light.

Etymology

Derived from the Greek prefix 'meta-' (meaning beyond, after, or transcending) combined with the word 'crystal,' signifying a material that functions beyond the limits of naturally occurring crystalline structures.

In the news

The article describes how researchers created a metacrystal by carving tiny slits into gold, allowing it to filter quantum light at room temperature instead of requiring extreme cooling. This represents a shift toward designing artificial materials rather than searching for natural ones.
