1. A method, comprising:
- generating, via a polyphase waveguide probe, at least one resultant field that synthesizes a wave front incident with a lossy conducting medium at a complex Brewster angle of incidence by substantially mode-matching the at least one resultant field to a Zenneck surface wave mode on a surface of the lossy conducting medium, the polyphase waveguide probe comprising a first charge terminal and a second charge terminal; and
adjusting the polyphase waveguide probe to improve the mode-matching of the Zenneck surface wave mode in response to detecting one or more conditions associated with the polyphase waveguide probe, wherein adjusting the polyphase waveguide probe comprises adjusting at least one of a phase or a magnitude on at least one of the first charge terminal or the second charge terminal.

Abstract
Disclosed are various embodiments for transmitting energy conveyed in the form of a guided surface-waveguide mode along a lossy conducting medium such as, e.g., the surface of a terrestrial medium by exciting a polyphase waveguide probe. A probe control system can be used to adjust the polyphase waveguide probe based at least in part upon characteristics of the lossy conducting medium.
