Data from: Evaluation of the Laguerre-Gaussian mode purity produced by 3D-printed microwave spiral phase plates

Dmitry Isakov, Yingwei Wu, Ben Allen, Chris Stevens, Patrick Grant & Greg Gibbons
Computer-aided design software and additive manufacturing provide flexibility in the direct fabrication of multi-material devices. This design and fabrication versatility has been investigated for the manufacture of dielectric spiral phase plates (SPP) to generate electromagnetic waves with helical wave-fronts. Three types of SPPs designed to produce an orbital angular momentum (OAM) mode number l=|1| were additively manufactured using multi-material extrusion and multijet fabrication methods. The phase mode and mode characteristics of transformed helical microwaves as...
