1. A waveguide system, comprising:

  • a coupling device that facilitates coupling a first guided electromagnetic wave onto an outer surface of a transmission medium, the coupling device positioned with respect to the transmission medium, the coupling device having a central axis that is not coaxially aligned with a longitudinal axis of the transmission medium, the first guided electromagnetic wave at least partially surrounding the outer surface of the transmission medium, the first guided electromagnetic wave propagating along the outer surface of the transmission medium without requiring an electrical circuit, wherein at least a portion of the first guided electromagnetic wave has an electromagnetic field structure that is external to the outer surface of the transmission medium, and the first guided electromagnetic wave having a wave propagation mode; and

    an antenna that facilitates transmission of a first wireless signal responsive to receiving the first guided electromagnetic wave from the outer surface of the transmission medium.
