Patent ID: 7710336

Claim:
A metamaterial having a negative refractive index and exhibiting a dielectric carrier material ( 12 ; 48 ), first electrically conductive sections ( 14 . 1 , 14 . 2 , 14 . 3 , 14 . 4 ) and second electrically conductive sections ( 16 . 1 , 16 . 2 ), characterized in that the dielectric carrier material ( 12 ; 48 ) is realized as a volume consisting of one piece that exhibits at least one inner area ( 50 ), which is prestructured by positive or negative fin or mesa structures ( 52 . 1 , 52 . 2 ) in the dielectric carrier material ( 48 ), and is covered with first sections ( 14 . 1 , 14 . 2 , 14 . 3 , 14 . 4 ) and second sections ( 16 . 1 , 16 . 2 ) such that the first sections form capacitive serial impedances when illuminated with an electromagnetic wave of a specific direction of propagation and polarization, while the second sections are arranged such that they form inductive shunt impedances upon illumination.
