HYBRID-MODE SCATTERING CHARACTERISTICS OF FINLINE IMPEDANCE DISCONTINUITIES

  • 摘要: 本文用混合模展開鰭線中的本征場,并應(yīng)用譜域法確定主模和高次模的傳播常數(shù)和譜域中的本征場,然后結(jié)合模匹配法分析鰭線阻抗不連續(xù)性的混合模散射特性。文中給出計算的單鰭前30個模,雙鰭前20個模的傳播常數(shù)和阻抗不連續(xù)性的主模散射參數(shù),計算結(jié)果與文獻發(fā)表的結(jié)果一致。有關(guān)數(shù)值收斂性問題亦在文中進行了討論。
    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.
