Claim:
1. A wireless electrical power transmission system based on nearfield coupled resonant circuits between a source unit and at least one load comprising: at least one first capacitor and at least one first inductor forming at least one first resonant circuit in said source unit for emitting electrical power, at least one second capacitor and at least one second inductor forming at least one a second resonant circuit, a resonance frequency of said at least one second resonant circuit being substantially equal to a resonant frequency of said at least one first resonant circuit, for receiving at least a part of the electrical power emitted by said at least one first resonant circuit and for delivering the at least a part of the electrical power to said at least one load, at least one detector for detecting a coupling condition of said at least one first and second resonant circuits, and at least one controller for controlling power transmission between said source unit and said at least one load, wherein said power transmission is at least one of interrupted, minimized and continued at a different emitted frequency, responsive to at least one of a detected critical- and overcritical coupling condition of said at least one first- and second resonant circuits.
