Abstract: Aspects of the subject disclosure may include, a system that facilitates detecting first electromagnetic waves propagating along a transmission medium are experiencing a first propagation loss, inducing second electromagnetic waves along the transmission medium to mitigate the first propagation loss, detecting that the second electromagnetic waves are experiencing a second propagation loss and inducing third electromagnetic waves along the transmission medium to mitigate the second propagation loss. To reduce radiation losses when transitioning from the first electromagnetic waves to second electromagnetic waves and transitioning from the second electromagnetic waves to the third electromagnetic waves, the system can be further adapted to use differing criteria for each transition. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, a device having a cylindrical coupler having a metallic shell that surrounds a transmission medium, wherein the cylindrical coupler launches a radio frequency signal from an aperture of the metallic shell as a guided electromagnetic wave that is bound to an outer surface of the transmission medium, and wherein the guided electromagnetic wave propagates along the outer surface of the transmission medium without requiring any electrical return path. An impedance matching element has a conductive trough within the metallic shell, wherein the impedance matching element couples the radio frequency signal to the cylindrical coupler via a coaxial feed point within the conductive trough, and wherein the conductive trough includes a first end forming a short circuit with the metallic shell and further includes a second end forming an open circuit within the metallic shell.

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.
