Experiments in the 3 GHz region are reported normal incidence of magnetostatic forward volume waves (MSFVW) on etched groove arrays. Significant mode conversion to standing spin wave resonances (SSWR) along the axis normal to the films has been observed and correlated to the SSWR spectrum. A criterion is derived which allows design of etched groove arrays with optimum bandwidth including the effects of the SSWR mode conversion. Suitable pass-band characteristics can be achieved by choice of etch groove depth.
