Metamaterials are engineered materials designed to possess properties not found in naturally occurring materials, achieved through their unique structure rather than their composition. These materials are fabricated with precisely arranged patterns at microscopic or smaller scales to interact with electromagnetic waves, sound, and other physical phenomena in unconventional ways. The ability to control wave propagation through structural design enables metamaterials to exhibit negative refractive index, perfect absorption of light or sound, and cloaking effects. Applications of metamaterials are vast and diverse, ranging from creating advanced optics and improving acoustic devices to enhancing the effectiveness of antennas and contributing to the development of stealth technology. Their potential continues to expand as researchers discover new ways to manipulate physical laws through structural innovation.
