Abstract

A new wireless power-relay system suitable for any scale or distance of power transmission and distribution, whether in-building, inter-building, intra-city, or long-distance/inter-city, primarily based on low-frequency magnetic resonance field coupling, but alternatively based on low-frequency E-M waves; with multiple stages of non-interfering send-and-receive pairs that realizes a “power relay” process, structure and system, repeatable and extendable to any distance; and employing efficient shielding for highly-directed rather than omnidirectional field and wave emission; and finally and importantly, employing field and wave-guiding structures to increase efficiency and reduce cost in built and un-built environments.
