Metamateriau; Metamaterial
Artificial material with physical properties beyond those of natural materials.
Left-handed material ; Matériau à main gauche
Material in which the phase velocity of the electromagnetic wave is negative. The optical index of this material is real but negative.
Split-ring resonators (SRR); circular resonators (RCC)
Cut circular resonators that exhibit a resonant frequency when a magnetic field parallel to their axis passes through them. The equivalent permeability of these resonators can become negative in the vicinity of this resonant frequency.
Vitesse de phase; phase velocity
Speed of change of the phase of a wave. This velocity can become negative in a left-handed material. In this case,...
