1. A guided surface waveguide probe comprising:
- a charge terminal configured to generate a guided surface wave comprising an electromagnetic field;
a support apparatus that supports the charge terminal above a lossy conducting medium, wherein the electromagnetic field generated by the charge terminal synthesizes a wave front incident at a complex Brewster angle of incidence (θ
i,B) of the lossy conducting medium, wherein the support apparatus supports the charge terminal at a top end of the support apparatus at a height above the surface of the lossy conducting medium that is at least four times an effective diameter of the char e terminal; and
a feed network electrically coupled to the charge terminal, the feed network providing a phase delay (Φ
) that matches a wave tilt angle (Ψ
) associated with the complex Brewster angle of incidence (θ
i,B) in the vicinity of the guided surface waveguide probe.
