We report here on dipolar coupling of spin waves propagating as guided modes of adjacent yttrium iron garnet stripes. Three stripes are placed parallel to each other and separated by gaps that are small enough to provide nearest-neighbor coupling. The origin of the coupling is the dipole field of the precessing magnetization vector. The micromagnetic numerical simulation, yielded spectra of spin waves through the magnonic structure. Analysis of those spectra revealed that the lateral structure can be used as a functional unit in planar magnonic networks – they can be utilized as a directional coupler, spin-wave multiplexer, or microwave power divider. Using Brillouin light scattering spectroscopy, we experimentally demonstrated spin-wave transport along the lateral stripes. We were able to control the spin-wave routing between the stripes by varying the bias angle of the magnetic field.
