We report on the experimental and theoretical investigation of spin-wave tunnelling through a mechanical gap in a ferromagnetic film. Samples with different gap widths were fabricated and the transmission of spin-wave pulses through the gaps was studied. Transmission through the gaps is possible due to the long-range character of the dipole-dipole interaction underlying dynamics of long-wavelength spin waves. By comparing our experimental results with the developed theoretical model, we demonstrate, that the local inhomogeneity of the static magnetisation and the internal field has a significant impact on the transmission.
