Abstract:
1. A medical device-powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply, 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 , the wireless receiver comprising: a load configured to power an implantable medical device using electrical power, wherein the load has an associated lossy object; and a second electromagnetic resonator adapted to be integrated with the implantable medical device or the load, the second electromagnetic resonator having a mode with a resonant frequency ω wherein the second electromagnetic resonator is configured to be wirelessly coupled to the first electromagnetic resonator to provide resonant, non-radiative wireless power to the second electromagnetic resonator from the first electromagnetic resonator; wherein the second electromagnetic resonator is configured to tailor electromagnetic fields with respect to the lossy object; and wherein the square root of the product of the respective Q factors is greater than 100.
