Abstract: Aspects of the subject disclosure may include, for example, a system that performs operations including receiving first electromagnetic waves on an outer surface of a transmission medium, detecting a degradation of a signal quality of the first electromagnetic waves due to first electric fields of the first electromagnetic waves inducing first currents in an obstruction disposed on the outer surface of the transmission medium, and generating second electromagnetic waves having second electric fields that induce second currents in the obstruction that are lower in magnitude than the first currents, the electromagnetic waves having a cutoff frequency. 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, 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.
