Beschreibung
In this work, the propagation behavior of orbital angular momentum (OAM) waves is numerically studied in scenarios commonly encountered in radio frequency (RF) communication links. In the RF domain, OAM waves comprise an orthogonal mode system, where the different OAM modes distinguish in their spacial phase pattern. To assist the design of OAM-based communication and sensing hardware, this work explores the fundamental behavior of radiated and guided OAM waves. This includes a general investigation of symmetry requirements the OAM mode system poses to an N-port and a more specific look at the impact of wave transmission over transmission lines, in free space, over ground, and through apertures. Additionally, the shielding and interference of OAM waves are studied.
