Abstract

In this paper we show how diffraction gratings with defects can generate beams with phase singularities, present an analysis of the phenomenon and discuss some applications. These beams and their effects have been studied at optical and at millimetre wavelengths. We describe a particularly efficient way of generating these beams at millimetre wavelengths employing a blazed grating with a defect.
