This study investigated the orbital angular momentum (OAM) multiplexing of a 5 GHz band microwave signal propagating along PVC pipe walls for a buried pipe inspection robot. The OAM modes that propagate along the PVC pipe wall were observed by electromagnetic simulation. The results showed that the...
