1. A device, comprising:
- a structure coupled to a transmission medium, wherein an electromagnetic wave propagating along the transmission medium is received at a first side of the structure, wherein the structure facilitates adjusting the 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, 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 that is further from the outer surface of the transmission medium, and wherein the electromagnetic wave and the adjusted electromagnetic wave propagate along the transmission medium without requiring an electrical return path.
