A study of the influence of geometry on spin wave propagation has been carried out using micromagnetic simulations in a composite waveguide structure made of Iron-Yttrium Garnet film with linearly varying widths. It is shown that increasing the distance between waveguides with linearly varying widths leads to a reduction in the frequency bandwidth due to the cutoff of the high-frequency region. The structure can be used as a spatial and frequency filter. Keywords: spin waves, magnonics, linear change of direction, multiport structure, waveguide system.
