摘要131Equation Chapter 1 Section 3论文题目 一种磁可调的 SIW 双模滤波器设计 摘 要本文首先介绍 SIW 技术的基本原理及其所涉及的传输模式；其次，本文旨在详细阐述双模谐振器所遵循的工作原理，并对微带线及其 SIW 谐振腔彼此之间存在的过渡结构，进行相对深入的细致阐述。随后，本文旨在详细论述以双模谐振腔理论为基础，而成功构建出的某特定 SIW 双模滤波器，再结合磁调谐的技术，实现一种新型磁可调带通滤波器，该滤波器装有四块铁氧体板。通过改变偏置磁场，滤波器的工作频率可以从 10GHz 调谐到 13.13GHz，显示出大约 11.27％的频率调谐范围。关键词：磁调谐，铁氧体，基片集成波导，双模滤波器IABSTRACTABSTRACTThis paper first introduces the principle and equivalent model structure of SIW technology, as well as the theory of dual-mode resonator and the transition structure between SIW resonator and microstrip line. 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................................
