摘要：A lineafized theory ofmagnetoatmospheric waves is developed where the restoring forces
are those of compressibility and magnetic pressure. An equation for resonance is derived. Reflection
and tunneling of upward propagating Alfvén waves in an ideal Magnetoatmosphere are considered. It
is shown that the magnetic field produces a reflecting nonabsorbing critical layer. Below the critical
layer, the solution of the problem can be written as a linear combination of an upward and a downward
propagating wave and above it the solution decays exponentially with the altitude. The location of the
critical layer and the magnitude of the reflection coefficient are determined and the conclusions are
discussed in cormeetion with the heating mechanism of the solar atmosphere
