1. A system, comprising:
- a guided surface waveguide probe configured to launch a guided surface wave along a surface of a lossy conducting medium, wherein the guided surface waveguide probe comprises a charge terminal elevated over the lossy conducting medium configured to generate at least one resultant field that synthesizes a wave front incident with the surface at a complex Brewster angle of incidence (θ
i,B) of the lossy conducting medium; and
a receiver configured to receive backscatter reflected by a remotely located subsurface object illuminated by the guided surface wave.

Abstract
Disclosed are various systems and methods for remote surface sensing using guided surface wave modes on lossy media. One system, among others, comprises a guided surface waveguide probe configured to launch a guided surface wave along a surface of a lossy conducting medium, and a receiver configured to receive backscatter reflected by a remotely located subsurface object illuminated by the guided surface wave. One method, among others, includes launching a guided surface wave along a surface of a lossy conducting medium by exciting a charge terminal of a guided surface waveguide probe, and receiving backscatter reflected by a remotely located subsurface object illuminated by the guided surface wave.
