摘要： Aspects of the subject disclosure may include, for example, a system having a plurality of transmitters for launching, according to a signal, instances of first electromagnetic waves having different phases to induce propagation of a second electromagnetic wave at an interface of a transmission medium, the second electromagnetic wave having a non-fundamental wave mode and a non-optical operating frequency, wherein the plurality of transmitters has a corresponding plurality of antennas. A reflective plate is spaced a distance behind the plurality of antennas relative to a direction of the propagation of the second electromagnetic wave. Other embodiments are disclosed.

摘要： A radio frequency (RF) communications system may include a local RF communications device and an RF antenna coupled to the local RF communications device. The RF antenna may include a cavity backing housing, a conical RF launch structure having an apex positioned within the cavity backing housing, and an elongate electrical conductor having a proximal end extending through the apex of the conical RF launch structure and a distal end spaced apart from the conical RF launch structure to define an elongate RF coverage pattern. The system may further include at least one remote RF communications device within the elongate RF coverage pattern to wirelessly communicate with the local RF communications device.

摘要： 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.

摘要： Aspects of the subject disclosure may include, for example, a coupler that includes a tapered collar that surrounds a transmission wire. A coaxial coupler, that surrounds at least a portion of the transmission wire, guides an electromagnetic wave to the tapered collar. The tapered collar couples the electromagnetic wave to propagate along an outer surface of the transmission wire. Other embodiments are disclosed.
