Method for generating a plurality of currents each having a frequency

A method for generating, from a first electric current including at least a first frequency component having a first frequency, a plurality of second currents each having a second respective frequency component, the method comprising the following steps:

• supplying a frequency distributor including:
• a first set of pillars, each pillar comprising a stack of layers superimposed in a stacking direction, the stack comprising at least:
• a free layer made from a first magnetic material,
• a fixed layer made from a second magnetic material, and
• a barrier layer made from a third nonmagnetic material, the barrier layer separating the free layer from the fixed layer in the stacking direction,
• at least one control member able to generate a second electric current,
• a coupling member, and
• a plurality of electrical output conductors, each electrical output conductor being able to supply an electrical device with a respective second electric current,
• being able, when the pillar is passed through by a direct current and is not excited by the coupling member, to generate, in the direct current, a third frequency component having a frequency called resonance frequency of said pillar,
• generating a plurality of second electric currents, each pillar of the first set being passed through by a second respective current in the stacking direction,
• exciting, by the coupling member, each pillar of the first set with an electromagnetic field having the first frequency, the ratio between twice the resonance frequency of each pillar of the first set and the first frequency being equal, to within ten percent, to a first natural integer,
• generating, by each pillar of the first set, a second frequency component in the second respective current, and
• supplying, with each second current, a corresponding electrical device via a respective output conductor.
