1. A method, comprising:
- receiving, by a waveguide system including a waveguide structure, a first communication signal;
launching, by the waveguide system, an electromagnetic wave according to the first communication signal; and
inducing by the waveguide system, according to the electromagnetic wave, a first guided electromagnetic wave on an outer surface of an insulation layer having a tapered end, wherein a portion of the insulation layer has a substantially uniform outer diameter, wherein the portion of the insulation layer is within the waveguide structure, wherein the tapered end is outside of the waveguide structure, wherein the insulation layer covers a first portion of a conductor, and wherein the insulation layer enables a first radial dimension of the first guided electromagnetic wave to increase as the first guided electromagnetic wave propagates longitudinally along the tapered end towards a second portion of the conductor.
