  • Patent number: 11362438
    Abstract: In accordance with one or more embodiments, a guided wave launcher includes an array of antennas configured to generate near field signals. A controller is configured to: select, in response to a first control signal, at least one of a plurality of guided wave modes; and adjust beam steering parameters of the array of antennas according to the selected one(s) of the plurality of guided wave modes. The near field signals combine to induce a guided electromagnetic wave having the selected one(s) of the plurality of guided wave modes, wherein the first guided electromagnetic wave is guided by the transmission medium and propagates along the transmission medium without requiring an electrical return path.
