Abstract. By means of consistent solution of motion equation for magnetization the consideration of dissipation for magnetostatic surface waves (MSSW) propagating on in-plane magnetized ferrite plate is considered. It is revealed the existence of dissipative branch backward MSSW laying higher on frequency relative to the main spectrum of forward MSSW and so the limitation on top of wave number maximum values for both spectrum branches. It is investigated the limitation of spectrum by damping parameter and the plate thickness role in alignment of wave length. It is carried out the comparison with before published experimental results and the recommendations for the new experiments position are proposed.

Key words: ferrite, magnetostatic waves, dissipation.
