What is meant by metamaterial?
What is meant by metamaterial? Metamaterials are composite media that can be engineered to exhibit unique electromagnetic properties. Made up from subwavelength building blocks (most often based on metals), these metamaterials allow for extreme control over optical fields, enabling effects such as negative refraction to be realized. What are the properties of metamaterial? Properties of metamaterialsInvisibility. Due to their peculiar optical capabilities (wavelength shorter than visible light), metamaterials can be invisible. Acoustic control. Negative electrical permittivity and magnetic permeability. What are some examples of metamaterials? Some examples of available metamaterials are negative index metamaterials, chiral metamaterials, plasmonic metamaterials, photonic metamaterials,...
