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.
