Abstract :
Negative refraction through a fishnet related metamaterial is demonstrated at 0.5 THz. This characterization is based on refraction angle determination through a prism-like structure. The measurements are performed by means of a goniometric time-domain spectroscopy system while a numerical assessment is carried out by full wave electromagnetic analysis.
