Zusammenfassung:PROBLEM TO BE SOLVED: To achieve efficient wireless energy transmission in the direction of a wide range over a middle distance and over the positional relationship of a resonator, suitable for charging and power supply of various types of electronic devices (electronic devices and electronic apparatuses) or concurrent power supply and charging.SOLUTION: There is explained improved capability for a supply source resonator coupled to an energy source and having a Q factor Q>100 and a specific size xand a second resonator coupled to energy drain positioned at a distance D from the supply source resonator and having a Q factor Q>100 and a specific size x. In this case, the supply source resonator and the second resonator are coupled to exchange energy in a wireless manner between the supply source resonator and the second resonator.SELECTED DRAWING: Figure 1 【課題】様々な電子デバイス(電子装置、電子機器)の充電、電力供給、又は同時の電力供給と充電に適した、中距離にわたる広範囲の方向および共振器の位置関係にわたる、効率的な無線エネルギー伝送を提供する。【解決手段】エネルギー源に結合され、QファクタQ1>100及び特有サイズx1を有する供給源共振器と、供給源共振器から距離Dに位置するエネルギードレインに結合され、QファクタQ2>100及び特有サイズx2を有する第2の共振器とのための改善された能力が説明され、この場合、供給源共振器および第2の共振器が、供給源共振器と第2の共振器との間でワイヤレスでエネルギーを交換するように結合される。【選択図】図1
