Embodiment Construction

[0039] First, some terminology should be established to provide clarity in the discussion of the concepts followed. First, a formal distinction is drawn between radiating and directing electromagnetic fields, as contemplated herein.

[0040] As contemplated herein, radiated electromagnetic fields include electromagnetic energy emanating from a source structure in the form of waves not confined by waveguides. For example, a radiated electromagnetic field is typically a field that leaves an electrical structure such as an antenna and propagates through the atmosphere or other medium and is not confined by any waveguide structure. Once radiated electromagnetic waves leave an electrical structure such as an antenna, they continue to propagate in a propagation medium (such as air) independent of their source until they are dissipated, regardless of whether the source continues to operate. Once electromagnetic waves are radiated, they are irrecoverable unless intercepted, and if no...

Abstract

Various embodiments are provided for site specification for directional guided surface wave transmission in a lossy media. In one embodiment, a probe site includes a propagation interface including first and second regions comprising different lossy conducting mediums; and a guided surface waveguide probe which is positioned adjacent to the first and second regions and 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).
