1. A method, comprising:
- exciting a first charge terminal and a second charge terminal of a polyphase waveguide probe with excitation voltages to synthesize a plurality of fields that substantially match a guided surface-waveguide mode of the lossy conducting medium to transmit energy along a surface of the lossy conducting medium via a radial surface current, the first charge terminal positioned at a defined height over the lossy conducting medium and the second charge terminal positioned below the first charge terminal by a defined distance;
detecting a change in operating conditions associated with the polyphase waveguide probe comprising detecting a change in an electric field strength associated with the radial surface current or detecting a change in conductivity of the lossy conducting medium; and
in response to the detected change, adjusting the polyphase probe to improve the matching of the guided surface waveguide mode.

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.
