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 also the limitation on top of wave number maximum values for both spectrum branches. The role of dissipation in the forming of dispersion properties of real and imaginary wave number parts is investigated. The comparison with properties of electromagnetic waves in anomalous dispersion region is carried out. 

Key words: ferrite, magnetostatic waves, dissipation.
