Magnetic coupling device with reflective plate and methods for use therewith

A coupling device comprising:

• receiving means for receiving a radio frequency signal conveying data;
• a cavity resonator, that electromagnetically couples the radio frequency signal to a wire as a guided electromagnetic wave that is guided by the wire;
• a dielectric portion that secures the wire adjacent to the cavity resonator;
• and
• reflecting means that reduces electromagnetic emissions from the cavity resonator, wherein the reflecting means is spaced a distance from the cavity resonator corresponding to substantially one-half of a wavelength of the radio frequency signal in the dielectric portion.

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 guided by an outer surface of the transmission medium,
• reducing emissions from the cavity resonator via a reflective plate;
• wherein a dielectric portion secures the transmission medium adjacent to the cavity resonator and provides a spacing between the cavity resonator and the reflective plate, and wherein the spacing corresponds to substantially one-half of a wavelength of the signal.
