Launcher and coupling system to support desired guided wave mode
First Claim
1. A launcher comprising:
- a hollow waveguide that guides a first electromagnetic wave conveying data from a transmitting device; and
a dielectric stub coupler that receives the first electromagnetic wave from the hollow waveguide to form a second electromagnetic wave that propagates along a portion of the dielectric stub coupler adjacent to a transmission medium, wherein the second electromagnetic wave has a first guided wave mode and a second guided wave mode, and wherein the portion of the dielectric stub coupler has a length that supports suppression of the first guided wave mode in a third electromagnetic wave that propagates along a surface the transmission medium without requiring an electrical return path.

Abstract
Aspects of the subject disclosure may include, for example, a launcher that includes a hollow waveguide that guides a first electromagnetic wave conveying data from a transmitting device. A dielectric stub coupler receives the first electromagnetic wave from the hollow waveguide to form a second electromagnetic wave that propagates along a portion of the dielectric stub coupler adjacent to a transmission medium, wherein second electromagnetic wave propagates along the dielectric stub coupler via a first guided wave mode and a second guided wave mode, and wherein the portion has a length that supports a coupling of the second guided wave mode for propagation along an outer surface of the transmission medium.
