❓ Frequently Asked Questions
What are metamaterials?
Metamaterials are artificially engineered materials whose structure, not composition, gives them unusual electromagnetic properties, allowing control of light and waves in ways not found in nature.
What does negative refractive index mean?
A negative refractive index means light bends opposite to normal at interfaces, enabling unusual effects such as reversed Snell's law and potential advances in imaging and cloaking.
What is cloaking in metamaterials?
Cloaking uses metamaterials to guide light around an object, making it appear invisible for certain wavelengths, though practical devices are limited by bandwidth and fabrication.
