Abstract
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.
