Experiments on the Goos-H\"{a}nchen shift with negative and positive index of refraction materials

~ The negative Goos-H\"{a}nchen shift occurs when a beam of radiation having a finite transverse extent undergoes total internal reflection at a positive to negative index of refraction interface, hence the reflected beam experiences a negative lateral shift. This phenomenon has been predicted for materials with a negative index of refraction. We investigate a composite wire and split-ring resonator medium between 8-12 GHz, based on that first implemented by [1]. In addition, we present an experiment to investigate the Goos-H\"{a}nchen shift and show preliminary results on transmission, refraction, and total internal reflection.
