Metamaterials: Fundamentals and Applications

This lecture covers the fundamentals and applications of metamaterials, discussing how materials interact with electromagnetic radiation based on the relationship between the illumination wavelength and feature size. It explains the concept of metamaterials made from nanostructures or 'artificial atoms' to behave as homogeneous materials. A comparison is made between metamaterials and photonic crystals in terms of fabrication, response to individual atoms, and operation frequency.
