Abstract:
Various examples are provided for site specification for directional guided surface wave transmission in a lossy media. In one example, a probe site includes a propagation interface including first and second regions comprising different lossy conducting mediums. A guided surface waveguide probe positioned adjacent to the first and second regions can generate at least one electric field to launch a guided surface wave along the propagation interface in a radial direction defined by the first region and restricted by the second region. The propagation interface can also include additional regions comprising the same or different lossy conducting mediums. One or more of the regions can be prepared regions. In some cases, the regions can correspond to a terrestrial medium (e.g., a shoreline) and water (e.g., seawater along the shoreline).
