Abstract

We report the results of a Snell’s law experiment on a negative index of refraction material in free space from 12.6 to 13.2 GHz. Numerical simulations using Maxwell’s equations solvers show good agreement with the experimental results, confirming the existence of negative index of refraction materials. The index of refraction is a function of frequency. At 12.6 GHz we measure and compute the real part of the index of refraction to be 1.05. The measurements and simulations of the electromagnetic field profiles were performed at distances of 14λ and 28λ from the sample; the fields were also computed at 100λ.
