A quasi-optical coupling system launches and extracts surface wave communication transmissions from a wire. At millimeter-wave frequencies, where the wavelength is small compared to the macroscopic size of the equipment, the millimeter-wave transmissions can be transported from one place to another and diverted via lenses and reflectors, much like visible light. Transmitters and receivers can be positioned near telephone and power lines and reflectors placed on or near the cables can reflect transmissions onto or off of the cables. The lenses on the transmitters are focused, and the reflectors positioned such that the reflected transmissions are guided waves on the surface of the cables. The reflectors can be polarization sensitive, where one or more of a set of guided wave modes can be reflected off the wire based on the polarization of the guided wave modes and polarization and orientation of the reflector.

An apparatus, comprising: a transmitter configured to emit a focused transmission, wherein a wavelength of the transmission corresponds to a millimeter-wave band, and wherein the focused transmission is directed to a focal plane of a reflector; andthe reflector, positioned with respect to a wire,

The apparatus of claim 12, further comprising: a repeater that repeats the incoming transmission received by the receiver resulting in an amplified transmission; anda transmitter that transmits the amplified transmission to a second reflector that reflects the amplified transmission in the direction substantially parallel to the wire in another direction toward which the incoming transmission was travelling before being reflection, wherein the amplified transmission comprises a guided wave on a surface of the wire. 16. The apparatus of claim 15 wherein the reflector and the second reflector are two sides of a reflecting device. 17. The apparatus of claim 16, wherein the receiver and the transmitter are communicably coupled and on substantially opposite sides of the reflecting device. 18.
