1. A method, comprising:
- coupling a receiving structure to a lossy conducting medium; and
mode-matching the receiving structure with a guided surface wave established on the lossy conducting medium, where a traveling wave phase delay (Φ
) of the receiving structure is matched to a wave tilt angle (Ψ
) associated with the guided surface wave, the wave tilt angle (Ψ
) based at least in part upon characteristics of the lossy conducting medium in a vicinity of the receiving structure.
