Then a SIW dual-mode filter based on the theory of dual-mode resonator is introduced. Combined with the technology of magnetic tuning, a new magnetically tunable bandpass filter is realized. The filter is equipped with four ferrite plates. . By changing the bias field, the filter's operating frequency can be tuned from 10 GHz to 13.13 GHz, showing a frequency tuning range of approximately 11.27%.Keywords: Magnetically Tunable, ferrite, siw, dual-mode filterII目录目 录第一章 绪 论...................................................................................................................11.1 研究工作的背景与意义......................................................................................11.2 时域积分方程方法的国内外研究历史与现状..................................................11.3 本文的主要贡献与创新......................................................................................21.4 本论文的结构安排..............................................................................................2第二章 时域积分方程基础................................
