| contents | Utilization of spin-wave transducers for radio-frequency signal processing provides significant potential due to intrinsic tunability, scalability and nonlinearity. However, such components can exhibit passband ripples diminishing their operation and functionality. Here, we experimentally identify the electromagnetic crosstalk (EM) as a major source of passband ripples and provide a simple analytic model to predict the impact on device operation. The results are in good agreement with the experimental observation. In addition, we test multiple transducer geometries to identify operational regimes and minimize the EM impact. Finally, the effect of nonlinear device operation on the passband ripples is addressed, which is of relevance for the exploitation of the spin-waves intrinsic nonlinear traits. |
