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.
