Excited spin waves in strips are studied by detecting electrical signals with the use of a spin rectification effect. Through a meander control line, a periodic magnetic field is applied on the strips. Spin wave modes strongly depends on the periodic magnetic field. In a short period sample, we find spin wave coupling effect controlled by the periodic magnetic field, which can be used as a tunable spin wave filter.
