Abstract: Aspects of the subject disclosure may include, for example, receiving, by a receiver of a first device, electromagnetic waves that are generated by a transmitter of a second device at a physical interface of a transmission medium, where the electromagnetic waves propagate without requiring an electrical return path, and where the electromagnetic waves are guided by the transmission medium to the receiver of the first device. The first device can detect a physical object in proximity to the transmission medium according to a change in the parameter associated with the electromagnetic waves. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a system for receiving a first electromagnetic wave supplied by a dielectric antenna in a first position, where the first electromagnetic wave propagates along an outer surface of a feedline of the dielectric antenna, receiving a second electromagnetic wave supplied by the dielectric antenna in a second position, where the second electromagnetic wave propagates along the outer surface of the feedline of the dielectric antenna, measuring a ratio of a first signal strength of the first electromagnetic wave and a second signal strength of the second electromagnetic wave, detecting that the ratio is below a threshold, and adjusting an operational characteristic of a system to increase the ratio. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a transmission device that includes a transmitter that generates a first electromagnetic wave to convey data. A coupler couples the first electromagnetic wave to a single wire transmission medium having an outer surface, to forming a second electromagnetic wave that is guided to propagate along the outer surface of the single wire transmission medium via at least one guided wave mode that includes an asymmetric or non-fundamental mode having a lower cutoff frequency. A carrier frequency of the second electromagnetic wave is selected to be within a limited range of the lower cutoff frequency, so that a majority of the electric field is concentrated within a distance from the outer surface that is less than half the largest cross sectional dimension of the single wire transmission medium, and/or to reduce propagation loss. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a coupler including a receiving portion that receives a first electromagnetic wave conveying first data from a transmitting device. A guiding portion guides the first electromagnetic wave to a junction for coupling the first electromagnetic wave to a transmission medium. The first electromagnetic wave propagates via at least one first guided wave mode. The coupling of the first electromagnetic wave to the transmission medium forms a second electromagnetic wave that is guided to propagate along the outer surface of the transmission medium via at least one second guided wave mode that differs from the at least one first guided wave mode. Other embodiments are disclosed.
