Abstract
Disclosed are various systems and methods directed to the launching of a guided surface wave embodying a modulated signal using a guided surface waveguide probe. A modulated signal is generated and coupled to a guided surface waveguide probe. A resulting guided surface wave is launched that decays exponentially as a function of distance.
