  We study spin-wave transport in a microstructured Ni81Fe19 waveguide
exhibiting broken translational symmetry. We observe the conversion of a beam
profile composed of symmetric spin-wave width modes with odd numbers of
antinodes n=1,3,... into a mixed set of symmetric and asymmetric modes. Due to
the spatial homogeneity of the exciting field along the used microstrip
antenna, quantized spin-wave modes with an even number n of antinodes across
the stripe's width cannot be directly excited. We show that a break in
translational symmetry may result in a partial conversion of even spin-wave
waveguide modes
