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, and in response to the first electromagnetic wave, forms 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, wherein the dielectric stub coupler generates a third electromagnetic wave in response to the second electromagnetic wave that propagates along a surface the transmission medium via the second guided wave mode, wherein the portion of the dielectric stub coupler has a length from an end of the hollow waveguide to an end of the dielectric stub coupler outside of the hollow waveguide, and wherein the length supports suppression of the first guided wave mode in the third electromagnetic wave.

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.
