Since the Maxwell’s era, electromagnetic waves were believed to be travelling in a straight line in a manner not very different from a light ray. However, we have in this work proven the feasibility of transmitting energy through a curved surface. Method: To start with, a single-wire energy harvester was constructed and used to detect by contact an incoming surface plasma wave. Separately, an RF plasma at 26 kHz was generated and transmitted from one beaker of pure water (transmitting end), then through a curved plastic water tube, finally to another beaker of pure water (receiving end). Results: An electromagnetic energy was successfully detected with no conductor at the receiving end using the single-wire receiver. The transmission channel was a curved water tube, thus ruling out of any possibility of LOS transmission. The voltage detectable at receiving end was in general lower than that at the transmission end. However, the transmission efficiency as observed at the receiving end was found to be weakly dependent of the transmission range. No voltage was detected when the surface of the curved water tube was in contact with a human. Conclusion: Overall, an electromagnetic energy was successfully transmitted through a curved surface in the absence of any conductor. Our results suggest that harvesting lightning energy through a wet surface is close to a reality.
