    Abstract:
    Recent experiments that demonstrated the negative refraction of light were presented. The refraction at the interface between a positive-index material and a negative index material teared the wave apart, leaving no single negatively refracted wave. The researchers used a positive-index Teflon wedge as a control sample, which caused the path of a microwave beam to exit the sample at a positive angle.
