DEVICE FOR NEUROMORPHIC PROCESSING OF MICROWAVE SIGNALS BASED ON THE PRINCIPLES OF MAGNONICS Russian patent published in 2022 - IPC G06N7/08 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in telecommunication and microwave measurement systems as a physical neural network for analog processing of a microwave signal. The microwave signal processing device contains a ferrite film, which can be made in the form of a film of yttrium iron garnet 1, grown, for example, on a gadolinium gallium garnet substrate. The ferrite film is placed between the poles of the magnetic system 2 in an external constant uniform magnetic field directed perpendicular to the film surface. Microwave inputs 3 are connected to an array of Q input multi-element microstrip antennas 4, consisting of N elements located above the surface of the ferrite film (Q and N are integers). An array of S output multi-element microstrip antennas 5 consisting of M elements (S and M are integers) is located above the film surface at a distance that ensures the location of the input antennas in the far zone. In this case, the distance between the elements of microstrip antennas can be set in the process of designing the device. The output microstrip antennas are connected to the microwave outputs 6.

EFFECT: creating the possibility of adjusting the weight coefficients of input and output neurons and limiting the maximum level of the output signal.
