APPARATUS AND METHODS FOR LAUNCHING GUIDED WAVES VIA CIRCUITS
First Claim
1. A method, comprising:
- generating first electromagnetic waves, by a waveguide system having a plurality of circuits, each of the plurality of circuits having a corresponding one of a plurality of radiating elements; and
directing, at least partially by a reflective plate of the waveguide system, instances of the first electromagnetic waves to an interface of a transmission medium to induce a second electromagnetic wave along a surface of the transmission medium, wherein the second electromagnetic wave propagates along the surface of the transmission medium without utilizing an electrical return path, and wherein the second electromagnetic wave has a non-fundamental wave mode and a non-optical operating frequency.

Abstract
Aspects of the subject disclosure may include, for example, a system having a plurality of transmitters for launching, according to a signal, instances of first electromagnetic waves having different phases to induce propagation of a second electromagnetic wave at an interface of a transmission medium, the second electromagnetic wave having a non-fundamental wave mode and a non-optical operating frequency, wherein the plurality of transmitters has a corresponding plurality of antennas. A reflective plate is spaced a distance behind the plurality of antennas relative to a direction of the propagation of the second electromagnetic wave. Other embodiments are disclosed.
