Abstract: Aspects of the subject disclosure may include, for example, a system including a frequency mixer that combines a signal and a carrier wave to form a combined signal, and a transmitter that generates a transmission based on the combined signal. The system can also include a coupling device that emits the transmission as an electromagnetic wave guided by an outer surface of a transmission medium. The electromagnetic wave can propagate longitudinally along the surface of the transmission medium and at least partially around the surface of the transmission medium.

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, the first electromagnetic wave having at least one carrier frequency and corresponding wavelength. A coupler couples the first electromagnetic wave to a transmission medium having at least one inner portion surrounded by a dielectric material, the dielectric material having an outer surface and a corresponding circumference, wherein 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 dielectric material via at least one guided-wave mode that can include an asymmetric mode, wherein the at least one carrier frequency is within a microwave or millimeter-wave frequency band and wherein the at least one corresponding wavelength is less than the circumference of the transmission medium. Other embodiments are disclosed.

Abstract: A transmission device includes a coupler configured to convert a transmit signal to transmitted guided electromagnetic waves that propagate along a surface of a transmission medium without requiring an electrical return path, the coupler further configured to convert to a receive signal, received guided electromagnetic waves that propagate along the surface of the transmission medium without requiring an electrical return path. A housing is configured to provide environmental protection to the coupler. The housing includes an aperture section configured to pass the transmitted guided electromagnetic waves from the coupler through an aperture side of the housing, the aperture section further configured to pass the received guided electromagnetic waves to the coupler through the aperture side of the housing. The housing also includes a non-aperture section configured to absorb radio frequency (RF) signals in a frequency range of the transmit signal and a frequency range the receive signal.

Abstract: In accordance with one or more embodiments, a waveguide system includes a transmission device configured to send and receive guided electromagnetic waves that propagate along a surface of a power line without requiring an electrical return path. The waveguide system further includes a magnetic core that surrounds the power line, a first winding around the magnetic core that generates a supply current in response a transmission current flowing through the power line and a power supply that converts the supply current to a supply voltage that powers the transmission device. The power supply automatically stabilizes power consumption by the transmission device in response to variations in the supply current caused by variations in the transmission current flowing through the power line.
