Abstract
A spectrum analyzer for a signal IRF comprising a plurality of frequencies fi comprises N entities each made up of a structure formed by a stack of magnetic and non-magnetic layers having in at least one of the magnetic layers a magnetic configuration in the shape of a vortex, the excitation modes of the magnetic configuration being suitable for detecting the frequencies contained in an incident signal in real time, each entity having a first lower electrode and a second upper electrode, a voltage-measuring device suitable for measuring an electric voltage showing the presence of a frequency fk in the analyzed signal IRF, the device being connected to the lower electrode and to the upper electrode, a measurement-processing device suitable for determining the value of the frequencies fk in the signal IRF, and a line carrying the signal to be analyzed to each of the entities.
