1. A device, comprising:

  • a transmitter that facilitates launching a first electromagnetic wave along a transmission medium, wherein the first electromagnetic wave propagates along the transmission medium without requiring an electrical return path; and

    a structure coupled to the transmission medium, wherein the first electromagnetic wave propagating along the transmission medium is received at a first side of the structure, and wherein the structure facilitates adjusting the first electromagnetic wave to generate at a second side of the structure an adjusted electromagnetic wave that propagates along the transmission medium away from the structure, and wherein the adjusted electromagnetic wave has an electric field intensity that is lower near an outer surface of the transmission medium than at an outer radial region.
