Signal processing device using magnetic film and signal processing method

摘要

A signal processing device includes a continuous film, a plurality of spin wave generators, and at least one signal detector. The continuous film includes at least one magnetic layer. The plurality of spin wave generators are provided on the continuous film in such a manner as to be in direct contact with the continuous film or be in contact with the continuous film while having an insulation layer interposed therebetween, and each has a contact surface with the continuous film in a dot shape and generates a spin wave in a region of the magnetic layer of the continuous film by receiving an input signal, the region being immediately under the contact surface. The signal detector is provided on the continuous film and detects, as an electrical signal, the spin waves generated by the spin wave generators and propagating through the continuous film.

1. A signal processing device comprising:
a continuous film including at least one magnetic layer; first and second spin wave generators which are provided on the continuous film in such a manner as to be in direct contact with the continuous film or be in contact with the continuous film via an insulation layer interposed therebetween, and each of which has a contact surface with the continuous film in a dot shape and generates a spin wave in a region of the magnetic layer of the continuous film by receiving an input signal, the region being immediately under the contact surface; and at least one signal detector which is provided on the continuous film and detects, as an electrical signal, the spin waves generated by the spin wave generators and propagating through the continuous film, wherein a straight line between the first and second spin wave generators and a straight line between the first spin wave generator and the at least one signal detector are on the continuous film, and a straight line between the first spin wave generator and the at least one signal detector and a straight line between the second spin wave generator and the at least one signal detector are non-overlapping.
