title = "Space Transformation for Vortex Beam Generation",
abstract = "An all-dielectric oblate cylindrical shaped reflecting lens is proposed. The plane wave emitted from a wave port can be transformed into a vortex wave after being transmitted through the proposed lens and reflected by a planar metallic surface. The space transformation concept is applied for theoretical design of the lens, which results in a graded permittivity distribution profile. The far-field patterns are numerically simulated and reported in order to validate the proposed microwave lens over a wide frequency range spanning from 8 GHz to 12 GHz. Such an all-dielectric microwave lens can be potentially fabricated by low-cost materials through three-dimensional (3D) printing technology.",
