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 preventing theft of energy transmitted as a guided surface wave along the surface of a terrestrial medium, by pulsing the transmitted energy and protecting authorized devices from the pulse. In one embodiment, a guided surface wave receive structure is configured to obtain electrical energy from a guided surface wave. An electrical load coupled to the guided surface wave receive structure. The electrical load is experienced as a load at an excitation source coupled to a guided surface waveguide probe that is generating the guided surface wave with an electrical field strength that may be selectively increased. A pulse protection circuit is employed to selectively protect the electrical load from an increase in electrical energy received by the guided surface wave receive structure when the electrical field strength is selectively increased, while unprotected circuits may be damaged or disrupted by the pulse.

摘要： Disclosed are various embodiments of a guided surface wave transmitter/receiver configured to transmit a guided surface wave at a first frequency and to receive guided surface waves at a second frequency, concurrently with the transmission of guided surface waves at the first frequency. The various embodiments can be configured to retransmit received power and applied the received power to an electrical load. The various embodiments of the guided surface wave transmitter/receiver also can be configured as an amplitude modulation (AM) repeater.

摘要： Disclosed is a system and method for disaster warning recovery including a power modulator. A location is determined for an area affected by an emergency event. An emergency message is generated that corresponds to the emergency event. The emergency message is transmitted by via a guided surface wave. The guided surface wave is launched by a guided surface waveguide probe. The power modulator is coupled to the guided surface waveguide probe.

摘要： Disclosed is a guided surface waveguide probe with a charge terminal that is elevated over a lossy conducting medium. A primary coil can be coupled to an excitation source within a substructure. A secondary coil can provide a voltage to the charge terminal with a phase delay (Φ) that matches a wave tilt angle (Ψ) associated with a complex Brewster angle of incidence (θi,B) associated with the lossy conducting medium. The primary coil can be configured to inductively couple to the secondary coil.

摘要： Various examples are provided for enhanced guided surface waveguide probes, systems and methods. In one example, a guided surface waveguide probe includes a charge terminal elevated over a lossy conducting medium, the charge terminal includes a upper terminal portion coupled to a lower terminal portion through a variable capacitance. A feed network is configured to couple an excitation source to the charge terminal and provide a voltage to the charge terminal with a phase delay that matches a wave tilt angle associated with a complex Brewster angle of incidence associated with the lossy conducting medium. In another example a method includes positioning a charge terminal over a lossy conducting medium, where the charge terminal includes an upper terminal portion coupled to a lower terminal portion through a variable capacitance. The method also includes adjusting a phase delay of a feed network to match a wave tilt angle associated with a complex Brewster angle of incidence associated with the lossy conducting medium, where the feed network is configured to couple an excitation source to the charge terminal and provide a voltage to the charge terminal with the phase delay.

摘要： Disclosed are various embodiments for transmitting energy conveyed in the form of a guided surface-waveguide mode along a lossy conducting medium such as, e.g., the surface of a terrestrial medium by exciting a polyphase waveguide probe. A probe control system can be used to adjust the polyphase waveguide probe based at least in part upon characteristics of the lossy conducting medium.

摘要： Disclosed are various embodiments of an electromagnetic hybrid phased array system. One such embodiment includes a guided surface waveguide probe, and a contrawound toroidal helix antenna collocated with the guided surface waveguide probe in which the contrawound toroidal helix comprises ring elements spaced from each other and wrapped around the guided surface waveguide probe. The system further includes a signal source applied to at least the guided surface waveguide probe, such that the guided surface waveguide probe and the contrawound toroidal helix contribute individual vertical electric fields to form a radiation pattern based on the phase and amplitude characteristics of the individual vertical electric fields.
