How Do Materials with Negative Refractive Index Function?

Click For Summary
SUMMARY

Materials with a negative refractive index, known as metamaterials, possess unique properties that allow them to bend light in unconventional ways. These materials have been artificially produced and are not merely theoretical constructs. Key properties include the ability to achieve negative values for both permittivity and permeability, which enable applications such as superlenses and cloaking devices. The discussion highlights a Wikipedia article that serves as a concise introduction to these materials and their characteristics.
