Abstract :
In this paper, a three-dimensional, fully-isotropic, broadband negative-refractive-index medium is proposed. The structure has a negative-index bandwidth of 24% and a simulated loss of 0.063dB/cell at the operating frequency of 1.5GHz (where n ≈ -1). The fabrication process for this metamaterial, which utilizes stereolithography, is described. This process allows for mass production of the metamaterial´s constitutive elements, making the construction of large slabs possible.
