The transmission coefficient of spin waves incident perpendicularly on 180°‐Bloch walls are calculated. A standard semiclassical continuum approximation is used and the results show typical wave interference effects. In particular the transmission coefficient is unity when twice the wall thickness equals an integral number of wave lengths.
