The Q factor of an axially symmetric surface wave excited in a cylindrical cavity partially filled with a magnetized plasma is studied as a diagnostic method utilizing microwaves for high density plasma. The computations of the Q factor are carried out by using Maxwell's equations and also by using the quasistatic approximation. The dependence of the observed Q factor on the plasma density is in agreement with the calculated one obtained from the rigorous treatment using Maxwell's equations rather than that of the approximation. The result is explained in terms of a field solution in the cavity in which the fields are pushed out from the plasma region as the plasma density increases. The observation of the dependence of the Q factor on the static magnetic field is not explained by the present computational treatments and the cause for this problem is discussed.
