Abstract

Abstract

The eigenfields in finline are expanded in terms of the hybrid modes. The propagation constants of the dominant mode and the higer modes as well as the associated eigenfields in the spectral domain are then determined by using the spectral domain method. Finally the hybrid-mode scattering characteristics of finline impedance discontinuities are analysed in combination with the mode-matching technique. The propagation constants of the first 30 modes in unilateral finline and the first 20 modes in bilateral finline as well as the scattering parameters of the impedance discontinuities are computed. The computed results agree well with the published data. The problems about the numerical convergence are also discussed.
