Towards a Chip-Scale Millimeter-Wave Spectrum/Signal Analyzer Using Spin-Wave Diffraction and Interference

A new class of device has been proposed that converts millimeter electrical signals into spin waves with micrometer wavelengths, with which computing can be done in a small footprint. The spin waves are then converted back into electrical signals. Essential for this is the design of proper transducers between the two domains. We have simulated an electrical-to-spin-wave transducer that shows improved bandwidth. We are developing a numerical simulation design tool that crosses between these domains.
