Site preparation for guided surface wave transmission in a lossy media
First Claim
1. A probe site, comprising:
- a propagation interface including a lossy conducting medium that extends along the propagation interface; and
a guided surface waveguide probe configured to launch a guided surface wave along the propagation interface, the guided surface waveguide probe including a charge terminal elevated at a height over the lossy conducting medium, a ground stake in the lossy conducting medium, and a feed network coupled between the ground stake and the charge terminal, wherein;
a portion of the lossy conducting medium is prepared to launch the guided surface wave; and
the feed network is configured to provide a phase delay that matches a wave tilt angle associated with a complex Brewster angle of incidence at a crossover distance from the guided surface waveguide probe in the lossy conducting medium.

Abstract
Aspects of a guided surface waveguide probe site and the preparation thereof are described. In various embodiments, the guided surface waveguide probe site may include a propagation interface including a first region and a second region, and a guided surface waveguide probe configured to launch a guided surface wave along the propagation interface. In one aspect of the embodiments, at least a portion of the first region may be prepared to more efficiently launch or propagate the guided surface wave. Among embodiments, the portion of the first region, which may be composed of the Earth, may be treated or mixed with salt, gypsum, sand, or gravel, for example, among other compositions of matter. In other embodiments, the portion of the first region may be covered, insulated, irrigated, or temperature-controlled, for example. By preparing the site, a guided surface wave may be more efficiently launched and/or propagated.
