Abstract: The, resonance frequency and Q value of the H021 mode cavity with a double separate bulb are calulated in this paper. Because the wall of the bulb is geometrical symmetric, the distribution of the permittivity is symmetric longitudinal. Owing to the existence of the top and bottom of the bulb, the change of the resoname frequency and Q valne is given by means of pertubation method.

Key words: Cavity, Maser
