1. A system, comprising:
- a guided surface waveguide probe adjusted to launch a first guided surface wave at a first frequency along a terrestrial medium, the guided surface waveguide probe comprising a charge terminal elevated over the terrestrial medium, and further comprising 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 a complex Brewster angle of incidence (θ
i,B) associated with the terrestrial medium in a vicinity of the guided surface waveguide probe; and
a portion of the guided surface waveguide probe being configured to operate as a receive circuit, the receive circuit being tuned to receive a second guided surface wave at a second frequency.

Abstract
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.
