How Metamaterials Bend Waves Nature Can't: The Subwavelength Structures Behind Negative Refraction, Superlensing and Advanced Antennas

Metamaterials are engineered composites whose unique electromagnetic properties stem from their subwavelength structures, not their constituent materials. This design allows them to manipulate waves in ways natural materials cannot, enabling phenomena like negative refraction and superlensing.
