1. An apparatus, comprising:
- a guided surface waveguide probe adapted to launch a first guided surface wave within a defined region, wherein a first frequency of operation of the guided surface waveguide probe establishes a first area of operation in which the first guided surface wave propagates that substantially coincides with a portion of the defined region; and
at least one additional guided surface waveguide probe adapted to launch a second guided surface wave within a the defined region, wherein a second frequency of operation of the at least one additional guided surface waveguide probe establishes a second area of operation in which the second guided surface wave propagates that substantially coincides with a different portion of the defined region,wherein individual ones of the guided surface waveguide probe and the at least one additional guided surface waveguide probe comprise a charge terminal elevated over a terrestrial medium configured to generate at least one resultant field that synthesizes a wave front incident at a complex Brewster angle of incidence (θ
i, B) of the terrestrial medium.

15. A method comprising:
-
installing a plurality of guided surface waveguide probes across a defined region having set boundaries; setting respective frequency values of operation for the plurality of guided surface waveguide probes that allow for respective areas of operation to be defined that in the aggregate illuminate the defined region with guided surface waves without extending past a defined distance outside a perimeter of the defined region, wherein a area of operation corresponds to a geographic area across which a guided surface wave propagates; and transmitting a plurality of guided surface waves by the plurality of guided surface waveguide probes at the respective frequency values that illuminate the defined region but do not extend past the defined distance outside the perimeter of the defined region, wherein individual ones of the plurality of guided surface waveguide probes comprise a charge terminal elevated over a terrestrial medium configured to generate at least one resultant field that synthesizes a wave front incident at a complex Brewster angle of incidence (θ
i,B) of the terrestrial medium. - View Dependent Claims (16, 17, 18, 19)
