- Metamaterials are engineered materials with properties derived from their internal architecture, not chemical composition.
- They can manipulate light, sound, and electromagnetic waves, enabling applications like invisibility cloaks and advanced biosensors.
- AI accelerates metamaterial design by solving the inverse design problem through generative models and simulation data.
- Metamaterials have strategic importance, with investments from governments like China, the US, and the UK.
- Fabrication methods vary by scale and property, including lithography, 3D printing, and self-assembly.
- Challenges include bridging the simulation-reality gap and gaining experimentalists' trust in AI-designed materials.
- Invisibility cloaks work by bending light around objects, but current versions are limited to single frequencies.
- Metamaterials also have practical uses in telecommunications, sensors, and aerospace due to their unique properties.
