Radio frequency signal correlator utilizing parametric pumping of spin waves

Abstract

Various embodiments of a magneto-acoustic spin-wave signal processing system are provided. In one embodiment, a system includes an acoustic wave transducer configured to produce surface acoustic waves in a plane of a magnetostrictive material, wherein the magnetostrictive material serves as a medium for spin waves traveling in the plane, and wherein the acoustic wave transducer is oriented such that the acoustic waves parametrically amplify the spin waves. In this way, signal processing systems achieve the benefits of both spin wave and acoustic wave devices, taking advantage of the low dispersion and high dynamic range of acoustic waves coupled with the tunability and nonlinear effects provided by spin waves.
