摘要： In accordance with one or more embodiments, a dielectric coupler includes a neck portion configured to receive a first electromagnetic waves from a hollow waveguide. A plurality of arms is configured to generate, responsive to the first electromagnetic waves, second electromagnetic waves along a surface of a transmission medium, wherein the plurality of arms each end at differing azimuthal orientations relative to the transmission medium and wherein the second electromagnetic waves propagate along the surface of the transmission medium without requiring an electrical return path. A splitter portion is configured to split the first electromagnetic waves among the plurality of arms.

摘要： Aspects of the subject disclosure may include, for example, a transmission device that includes a transmitter that generates a first electromagnetic wave to convey data, the first electromagnetic wave having at least one carrier frequency and corresponding wavelength. A coupler couples the first electromagnetic wave to a transmission medium having at least one inner portion surrounded by a dielectric material, the dielectric material having an outer surface and a corresponding circumference, wherein the coupling of the first electromagnetic wave to the transmission medium forms a second electromagnetic wave that is guided to propagate along the outer surface of the dielectric material via at least one guided-wave mode that can include an asymmetric mode, wherein the at least one carrier frequency is within a microwave or millimeter-wave frequency band and wherein the at least one corresponding wavelength is less than the circumference of the transmission medium. Other embodiments are disclosed.

摘要： Disclosed are various embodiments for transmitting energy conveyed in the form of a guided surface-waveguide mode along a lossy conducting medium such as, e.g., the surface of a terrestrial medium by exciting a polyphase waveguide probe. A probe control system can be used to adjust the polyphase waveguide probe based at least in part upon characteristics of the lossy conducting medium.

摘要： An apparatus providing a phase-matched interface between a driver device and a multibeam optoelectronic device, such as a VCSEL array device, is disclosed as well as various methods for utilization and manufacturing of the same. The interface device includes an input adapted to interface with the driver device, an output to interface with the multibeam optoelectronic device, and a power splitter to electrically connect the output to the input. The output includes a plurality of output contacts that each interface with one optoelectronic device among the plurality of optoelectronic devices of the multibeam optoelectronic device via one transmission line among a plurality of transmission lines having a common electrical length. In embodiments, the power splitter is a resistor-based power splitter that adjusts an overall impedance of the power splitter at each “tee” junction or intersection to provide an impedance-matched interface.
