Abstract

We consider a sophisticated localized light wave—the so-called focused X wave which possesses a strong exponential localization in its waist region and propagates faster than the speed of light in a vacuum or in a linear medium. We show how this wave—until now considered in the literature as a mathematical object only—could be generated in reality by making use of cylindrical diffraction gratings.
