NEGATIVE-INDEX METAMATERIALS • Optical properties of materials are governed by the electric permittivity ε and the magnetic permeability µ • Any collection of objects with size and spacing 0 Electrical plasmas, metals, thin wire structures Double Negative Materials ε < 0, µ < 0 Negative-Index metamaterials, not found in nature µ Double positive media ε > 0, µ > 0 dielectrics Mu-negative materials ε > 0, µ < 0 Gyromagnetic materials, magnetic plasmas? Classification of materials based on dielectric and magnetic properties ε 8
REAL NEGATIVE-INDEX METAMATERIALS • No naturally occurring NIM has ever been discovered! • Can combine two regions to store electrical and magnetic energy into a single cell of metamaterial • Inductor-capacitor resonance circuits • A theoretical curiosity until Smith et al experimentally demonstrated a negative refraction in the microwave using an array of copper strips and split-ring resonators in 2000 9
