Abstract

A three-dimensional (3D) infra-red conductive metamaterial proposed for 90 degrees one way polarization converter and asymmetric transmitter meta-device for linearly polarize light [1] is demonstrated. The metamaterial structure, which comprises of Spit Cube Resonator (SCR) pairs (figure Left: a-c) rotated by 90 degrees with respect to each other along the wave propagation axis, was fabricated by direct laser writing and selective electroless silver coating, a straightforward, novel technique producing mechanically and chemically stable 3D photonic structures [2-3]. The asymmetric transmission (A.T.) response of the structure results from asymmetric interplay of electric and magnetic resonant responses of the SCRs, and equips the structure with almost total opaqueness along one propagation direction versus satisfying transparency along the opposite one, for linearly polarized incident way of a specific polarization.
