Abstract
Aspects of the subject disclosure may include, for example, a coupling device including a receiving portion that receives a radio frequency signal conveying data from a transmitting device. A magnetic coupler magnetically couples the radio frequency signal to a transmission medium as a guided electromagnetic wave that is bound by an outer surface of the transmission medium. Other embodiments are disclosed.
Claims16
A coupling device comprising:
- a receiving portion that receives a radio frequency signal conveying data from a transmitting device;
- and
- an electromagnetic coupler, that electromagnetically couples the radio frequency signal to a transmission medium as a guided electromagnetic wave that is bound by an outer surface of the transmission medium, wherein the electromagnetic coupler comprises a cavity resonator that responds to the radio frequency signal by generating a magnetic field that induces the guided electromagnetic wave on the transmission medium via electromagnetic coupling and wherein the cavity resonator operates below a cut-off frequency of a desired guided wave mode.
A coupling device comprising:
- a receiving portion that facilitates receiving a radio frequency signal conveying data;
- and
- a cavity resonator, adapted to electromagnetically couple the radio frequency signal to a wire as a guided electromagnetic wave that is bound by the wire, wherein the cavity resonator responds to the radio frequency signal by generating a magnetic field that induces the guided electromagnetic wave on the wire via electromagnetic coupling and wherein the cavity resonator operates below a cut-off frequency of a desired guided wave mode.
A method comprising:
- receiving, via a receiving portion, a signal;
- and
- launching, via a cavity resonator, the signal on a transmission medium as a guided electromagnetic wave that is bound by an outer surface of the transmission medium, wherein the cavity resonator responds to the signal by generating a magnetic field that induces the guided electromagnetic wave on the transmission medium via electromagnetic coupling and wherein the cavity resonator operates below a cut-off frequency of a desired guided wave mode.
