Methods and apparatus for inducing a fundamental wave mode on a transmission medium

摘要

Aspects of the subject disclosure may include, for example, a system for generating electromagnetic waves having a fundamental wave mode, and directing the electromagnetic waves to an interface of a transmission medium for guiding propagation of the electromagnetic waves. Other embodiments are disclosed.

主权项

1. A method, comprising:
generating, by a waveguide system, instances of first electromagnetic waves that combine to form a combined electromagnetic wave having a fundamental wave mode, wherein a non-fundamental wave mode is at least substantially absent from the combined electromagnetic wave, and wherein the combined electromagnetic wave has a non-optical operating frequency; and directing, by the waveguide system, the combined electromagnetic wave to an interface of a transmission medium for guiding propagation of the combined electromagnetic wave without utilizing an electrical return path.
