摘要： Various examples are provided related to anisotropic constitutive parameters (ACPs) that can be used to launch Zenneck surface waves. In one example, among others, an ACP system includes an array of ACP elements distributed above a medium such as, e.g., a terrestrial medium. The array of ACP elements can include one or more horizontal layers of radial resistive artificial anisotropic dielectric (RRAAD) elements positioned in one or more orientations above the terrestrial medium. The ACP system can include vertical lossless artificial anisotropic dielectric (VLAAD) elements distributed above the terrestrial medium in a third orientation perpendicular to the horizontal layer or layers. The ACP system can also include horizontal artificial anisotropic magnetic permeability (HAAMP) elements distributed above the terrestrial medium. The array of ACP elements can be distributed about a launching structure, which can be excited with an electromagnetic field to facilitate the launch of a Zenneck surface wave.

摘要： Disclosed are various embodiments for fixing a navigational position using guided surface waves launched from guided surface wave waveguide probes at various ground stations. A guided surface wave is received using a guided surface wave receive structure. A reflection of the guided surface wave is received using the guided surface wave receive structure. An amount of time that has elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave is calculated. A location of the guided surface wave receive structure is determined based at least in part on the amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave.

摘要： 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.

摘要： Disclosed are various approaches for determining positions of a navigation unit and correcting for errors. The navigation unit can receive a guided surface wave using a guided surface wave receive structure. The navigation unit can then determine a potential location of the guided surface wave receive structure. Finally, the navigation unit can determine an accuracy of the potential location based at least in part on a secondary data source.
