Chip-scale Beamforming with Magnetostatic Spin-wave Transducer Arrays

This paper proposes a magnetostatic spin-wave (MSW) phased array which provides control over the angular distribution of spin-wave propagation in a magnetic film. A description of the array and magnetostatic simulation model is provided. Beamwidth scaling and beamscanning are shown to be well-predicted by classical antenna array theory. The proposed transducer array can be used to reduce diffraction loss for efficient spin-wave devices and also enables new applications for chip-scale analog signal processing directly at radio frequencies.
