摘要： A resonator for magnetic resonance applications has a conductor element proceeding in an extension direction, that operates with a resonance current at a resonance frequency oscillating therein in the extension direction. The conductor element is tuned to the resonance frequency and has an overall length in the extension direction that is smaller than half of the wavelength of the resonance frequency. The conductor element is a multi-layer conductor with layers that are electrically insulated from each other that, in said extension direction, have layer ends that are capacitively coupled with each other. During operation of the conductor element at the resonance frequency, respective layer currents flow in the layers in the extension direction that are substantially equal in magnitude.

摘要： A resonator for magnetic resonance applications has a conductor element that extends from a first conductor end to a second conductor end. During operation of the conductor element at a resonance frequency, a resonance current oscillates from the first conductor end to the second conductor end and back. The conductor ends are coupled with one another via a circuit that tunes the conductor element to the resonance frequency. The conductor element is fashioned as a multi-layer conductor with a number of layers that exhibit layer ends at the conductor ends. The circuit causes layer currents that are of different magnitudes among one another to flow in the layers during operation of the conductor element at the resonance frequency.
