Transmission, refraction, and focusing properties of labyrinth based left‐handed metamaterials

Abstract

In this present article, we studied the transmission, refraction and focusing properties of one, two and three dimensional labyrinth based left-handed metamaterials. We demonstrated that the proper periodic arrangement of labyrinth structures and wires results in left-handed transmission. By using a two dimen-sional labyrinth based left-handed slab, it is shown that it is possible to image the field emitted from source in sub-wavelength detail. Moreover, we demonstrated the focusing and negative refraction of elec-tromagnetic waves by a three dimensional labyrinth based left-handed slab.
