1. A guided surface waveguide probe, comprising:
- a charge terminal elevated over a lossy conducting medium, the charge terminal being configured to minimize atmospheric discharge;
a coil being configured to 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 (θ
i,B) associated with the lossy conducting medium, a top portion of the coil being recessed within a hollow region of the charge terminal; and
an excitation source coupled to the coil.

Abstract
Disclosed are various embodiments for eliminating or minimizing atmospheric discharge within the internal phasing coil of the guided surface waveguide probe. A guided surface waveguide probe comprises a charge terminal elevated over a lossy conducting medium. The shape of the charge terminal is designed to minimize atmospheric discharge. A top portion of a coil being configured to 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 is recessed within a hollow region of the charge terminal.
