摘要： The disclosed technology relates to a logic device based on spin waves. In one aspect, the logic device includes a spin wave generator, a waveguide, at least two phase shifters, and an output port. The spin wave generator is connected with the waveguide and is configured to emit a spin wave in the waveguide. The at least two phase shifters are connected with the waveguide at separate positions such that, when a spin wave is emitted by the spin wave generator, it passes via the phase shifters. The at least two phase shifters are configured to change a phase of the passing spin wave. The output port is connected with the wave guide such that the at least two phase shifters are present between the spin wave generator and the output port.

摘要： An arrangement for use in a matrix-vector-multiplier, comprising a stack of material layers arranged on a substrate, and a waveguide element formed in at least one material layer in the stack is disclosed. In one aspect, the arrangement further comprises a transducer arrangement which is coupled to the waveguide element. The transducer arrangement is configured to generate and detect spin wave(s) in the waveguide element, and wherein the waveguide element is configured to confine and to provide interference of the at spin wave(s) propagating therein. The arrangement further comprises a control mechanism comprising at least one control element coupled to the waveguide element, and a direct current electric source coupled to the at least one control element. The control mechanism, via the at least one control element, is configured to modify the phase velocity of the spin wave(s) propagating in the waveguide element.

摘要： The disclosed technology generally relates to computation devices, and more particularly to majority gate devices configured for computation based on spin waves. In one aspect, a majority gate device comprises cells that are configurable as spin wave generators or spin wave detectors. The majority gate device comprises an odd number of spin wave generators, and at least one spin wave detector. The majority gate device additionally comprises a waveguide adapted for guiding spin waves generated by the spin wave generators. The spin wave generators and the at least one spin wave detector are positioned in an inline configuration along the waveguide such that, in operation, interference of the spin waves generated by the spin wave generators can be detected by the at least one spin wave detector. The interference of the spin waves corresponds to a majority operation of the spin waves generated by the spin wave generators.

摘要： The present disclosure relates to a tunable magnonic crystal device comprising a spin wave waveguide, a magnonic crystal structure in or on the spin wave waveguide, and a magneto-electric cell operably connected to the magnonic crystal structure. The magnonic crystal structure is adapted for selectively filtering a spin wave spectral component of a spin wave propagating through the spin wave waveguide so as to provide a filtered spin wave. The magneto-electric cell comprises an electrode for receiving a control voltage, and adjusting the control voltage controls a spectral parameter of the spectral component of the spin wave via an interaction, dependent on the control voltage, between the magneto-electric cell and a magnetic property of the magnonic crystal structure.
