Abstract
Aspects of the subject disclosure may include, for example, a coupling device includes a circuit that receives a signal. At least one passive electrical circuit element generates an electromagnetic field in response to the signal. A portion of the electromagnetic field is guided by a surface of a transmission medium to propagate as a guided electromagnetic wave longitudinally along the transmission medium. Other embodiments are disclosed.
Claims14
A transmission device comprising:
- a transmitter that generates a signal;
- and
- at least one passive electrical circuit element, coupled to the transmitter, that generates an electromagnetic field in response to the signal, wherein the at least one passive electrical circuit element includes a first capacitor and a second capacitor;
- wherein the transmitter and the at least one passive electrical circuit element are configured such that a portion of the electromagnetic field is bound by an outer surface of a wire to propagate as a guided electromagnetic wave longitudinally along the wire, wherein the first capacitor is formed by a first plate placed in proximity to the wire and wherein the second capacitor is formed by a second plate placed in proximity to the wire, and wherein the electromagnetic field generated by the first capacitor and the second capacitor generates the guided electromagnetic wave to at least partially surround the outer surface of the wire.
