Abstract

Aspects of the subject disclosure may include, launching, by a plurality of launchers of a waveguide system, a wave mode that propagates along a transmission medium without requiring an electrical return path, detecting, by the waveguide system, that the wave mode has a propagation loss caused by an obstruction, and generating, by the plurality of launchers, an adjusted wave mode having an electric field structure that reduces the propagation loss of the obstruction. Other embodiments are disclosed.
