Abstract

In this paper, we calculate the parameters of typical transverse magnetic (TM) modes of microwave cavity; the fundamental modes (FM) and higher order modes (HOM). Calculations show that the TM ₀₁₀ mode of cylindrical cavity has an advantage of high characteristic impedance and drawback of small cavity size, and the TM ₀₁₀ and TM ₃₁₀ in cylindrical coaxial cavities have advantages of large cavity cross-section and some nearly equal parameters as Q-factor, frequency F and characteristic impedance Z. The results show agreement with the simulations
