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.
