Abstract: The effect of inner-rod oblique misalignment in a 9-GHz open coaxial resonator is studied by means of the software CST microwave studio. Results show that the oblique eccentric between the inner rod and outer wall have substantial influences on the field profile, resonant frequency, and Q factors of an open coaxial resonator. And the oblique misalignment has more serious effect than the parallel misalignment. So in the practical of engineering applications, we should try to avoid the occurrence of eccentric between the inner rod and outer wall during to technological factors.

Abstract: The effect of inner-rod parallel misalignment in a 9-GHz open coaxial resonator is studied by means of the software CST microwave studio. Results show that the parallel misalignments between the inner rod and outer wall have substantial influences on the field profile, resonant frequency, and Q factors of an open coaxial resonator. So in the practical of engineering applications, we should try to avoid the occurrence of eccentric between the inner rod and outer wall due to technological factors.

Abstract: In this paper, the computational formula of field distribution in a coaxial waveguide and the field distribution, resonant frequency and Q factors of open coaxial resonator are introduced. The S21 and the field profile of the TEM mode in a coaxial waveguide, and the field profile and E-field of the mode in a coaxial resonator is gained by the software CST microware studio. The truth that an open coaxial cavity is virtually a slow-varied section coaxial waveguide is gained.
