本文提出了多模谐振器的新概念，该概念基于介质棒中的 TM 模式操作。通过在分支配置中适当布置介电棒，可以证明存在新的基本本征模式谐振。在最简单的情况下，双模式操作可以通过 Y 形布置来实现。通过向适合平面制造的新型整体陶瓷添加更多分支，可以获得更多数量的基本模式。此外，非平面构造有利地是可能的，如在制造的过滤器原型中示例性示出的。
In this paper new concepts for multi-mode resonators are presented, which are based on TM-mode operation in dielectric rods. By proper arrangement of dielectric rods in branch configuration, new fundamental eigenmode resonances could be shown to be present. In the simplest case, dual-mode operation could be achieved by an Y-shape arrangement. Higher number of fundamental modes could be obtained by adding further branches to the novel mono-block ceramic, which is suitable for planar fabrication. Furthermore, non-planar constructions are advantageously possible as shown exemplarily at a manufactured filter prototype.
