Abstract:
1. A mobile wireless receiver for use with a first electromagnetic resonator coupled to a power supply and a second electromagnetic resonator coupled to at least one of a power supply and the first electromagnetic resonator, the first electromagnetic resonator having a mode with a resonant frequency ω 1 , an intrinsic loss rate Γ 1 , and a first Q-factor Q 1 =ω 1 /2Γ 1 and the second electromagnetic resonator having a mode with a resonant frequency ω 2 , an intrinsic loss rate Γ 2 , and a second Q-factor Q 2 =ω 2 /2Γ 2 , the mobile wireless receiver comprising: a load associated with an outdoor lighting unit that draws energy from the load to power a light source associated with the outdoor lighting unit; and a third electromagnetic resonator configured to be coupled to the load and movable relative to at least one of the first electromagnetic resonator and the second electromagnetic resonator, the third resonator having a mode with a resonant frequency ω wherein the third resonator is configured to be wirelessly coupled to at least one of the first electromagnetic resonator and the second electromagnetic resonator to provide resonant, non-radiative wireless power to the third electromagnetic resonator from at least one of the first electromagnetic resonator and the second electromagnetic resonator with a wireless energy transfer rate κ, and wherein the square root of the product of Q
