It is known from the literature of Cellular Nonlinear Networks (CNNs) and from the literature of coherent optical computing devices that wave phenomena can be used to solve a number of computing problems. We demonstrate the design of linear signal processing devices (spectrum analyzers, filters) using spin waves (magnetic excitations). The said spin waves are an especially attractive medium for on-chip, wave-based computing algorithms, as they are characterized by short wavelengths (<100 nm), high frequency (10-100 GHz), and carry energy in the electronvolt range. Spin-wave-based hardware could be a very natural implementation for wave-based computing, and could significantly outperform electrical (analog or digital) implementations.
