基于多模谐振模式融合的一体化成型介质波导滤波器构建方法及系统

本发明涉及介质波导滤波器技术领域，尤其为基于多模谐振模式融合的一体化成型介质波导滤波器构建方法及系统，根据目标滤波器的中心频率和带宽参数建立介质波导主体模型；在介质波导主体内构建多个谐振模式对应的谐振区域，使多个谐振模式分别在不同区域内形成电磁场分布；在多个谐振模式电磁场分布区域的交汇位置设置模式汇聚窗，模式汇聚窗是介质波导主体内的一个局部区域，其等效介电常数低于介质波导主体的介电常数，且模式汇聚窗作为多个谐振模式的统一能量交换节点。本发明中，通过在介质波导主体内设置等效介电常数更低的模式汇聚窗，为多个谐振模式建立了统一的能量交换节点，实现了基模与高阶模边缘电场的自然重叠与可控耦合。
