| 摘 要： | 运用有限差分法分析了不对称双脊波导传输特性,给出了不对称双脊波导的主模截止波长、单模带宽、场结构,并且与对称双脊波导的传输特性进行了比较,计算结果与对称的双脊波导相比较,不对称双脊波导减小了截止波长和单模带宽,因此可作为有效的双脊带宽滤波器,在微波工程中具有重要意义.数据对设计不对称脊波导具有重要参考价值.

| Abstract: | The transmission characteristics of asymmetrical double-ridge waveguide have been analyzed by the finite difference method. The cutoff wavelength, single-mode bandwidth, field pattern of the asymmetrical double-ridge waveguides have been presented, and they have also been compared with those of the symmetrical double-ridge waveguides. It shrinks the cutoff wavelength and single-mode bandwidth, so it is an effective ridge bandpass filter, and this is significant important in microwave engineering. The design data has been considered to be accurate enough and helpful in practical application. |
