Abstract :
In this work, fabrication and characterization of a negative-index metamaterial consisting of free-standing wire-pair composite structures is presented for application at THz frequencies. Complex index of refraction data is derived from amplitude- and phase-sensitive THz time-domain transmission and reflection measurements and compared with theoretical results. A first direct measurement of a negative index of refraction at 0.5 THz is demonstrated.
