Abstract
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.
Claims20
A coupler comprising:
- a tapered collar that surrounds a transmission wire;
- and
- a coaxial launcher, that surrounds at least a portion of the transmission wire, and guides an electromagnetic wave to the tapered collar and wherein the tapered collar couples the electromagnetic wave to be guided by the transmission wire to propagate, without requiring an electrical return path, along the transmission wire via a non-fundamental wave mode having an electromagnetic (EM) field pattern with a local minimum at an azimuthal orientation, and wherein the azimuthal orientation of the local minimum is aligned at a predetermined orientation with respect to the transmission wire.
A coupler comprising:
- a tapered collar that surrounds a transmission medium;
- and
- a coaxial launcher, that surrounds at least a portion of the transmission medium, and guides an electromagnetic wave to the tapered collar and wherein the tapered collar couples the electromagnetic wave to be guided by the transmission medium to propagate, without requiring an electrical return path, along the transmission medium via a non-fundamental wave mode having an electromagnetic (EM) field pattern with a local minimum at an azimuthal orientation, and wherein the azimuthal orientation of the local minimum is aligned at a predetermined orientation with respect to the transmission medium.
A coupler comprising:
- a tapered collar that surrounds an insulated wire;
- and
- a coaxial launcher, that surrounds at least a portion of the insulated wire, and guides an electromagnetic wave to the tapered collar and wherein the tapered collar couples the electromagnetic wave to be guided by the insulated wire to propagate, without requiring an electrical return path, along the insulated wire via a non-fundamental wave mode having an electromagnetic (EM) field pattern with a local minimum at an azimuthal orientation, and wherein the azimuthal orientation of the local minimum is aligned at a predetermined orientation with respect to the insulated wire.
