1. An apparatus, comprising:
- a plurality of guided surface waveguide probes configured to transmit guided surface waves along a lossy conducting medium to a certain geographic area,wherein an individual one of the guided surface waveguide probes comprises a charge terminal elevated over the lossy conducting medium configured to generate at least one resultant field that synthesizes a wave front incident at a complex Brewster angle of incidence of the lossy conducting medium;
a controller device configured to receive load status data and to signal for at least a subset of the guided surface waveguide probes to adjust transmission of the guided surface waves for the certain geographic area based at least in part on the load status data; and
a feed network electrically coupled to the charge terminal, the feed network providing a phase delay that matches a wave tilt angle associated with the complex Brewster angle of incidence associated with the lossy conducting medium in a vicinity of the individual one of the guided surface waveguide probes.
