Metamaterials

Metamaterials are engineered materials with unique properties not found in nature, achieved by structuring them on a small scale, typically at the wavelength of light. In solid-state physics and nonlinear optics, these materials can manipulate electromagnetic waves in extraordinary ways, such as bending light around objects or enhancing certain frequencies. Their unusual behaviors arise from their design rather than the composition of the material itself, leading to innovative applications in imaging, telecommunications, and even cloaking devices. Essentially, metamaterials allow us to control light and other waves in ways that traditional materials cannot.
