Experiments in the 3‐GHz region are reported for oblique incidence of magnetostatic forward volume waves (MSFVW) on an 8‐period uniform metallic grating of 140 &mgr;m periodicity. The MSFVW propagate in a 25‐&mgr;m‐thick epitaxial yttrium iron garnet film under normal magnetic bias. Insertion loss data and observed bandpass response are reasonably consistent with theory for MSFVW reflection through 90° by an array possessing a periodic impedance discontinuity.
