Flat-Lensed Spiral Phase Plate for OAM by elahe.shamooshaki is a document available to read on EtoBox.

The article presents a multi-layer phase-shifting surface (PSS) based flat-lensed spiral phase plate (SPP) designed for generating and focusing orbital angular momentum (OAM) beams at 60 GHz. The proposed structure combines lens and SPP functionalities, achieving low divergence angles and effective beam focusing, as verified through simulations and experiments. The results demonstrate the potential of this technology for enhancing communication capacity and spectral efficiency in millimeter-wave application
