摘要

当利用移动的柱塞改变微波圆柱腔谐振器的长度对其进行调谐时，不同模态的谐振频率可能相互重叠，从而产生噪声问题。因此，可调谐范围受不同模态频率重叠的影响。本文描述了一种简单而有效的方法来增加圆柱腔谐振器的特定模式的可调谐范围。为此，我们使用弯曲壁而不是平面壁作为移动壁来改变圆柱腔的长度。在HFSS的帮助下进行了观察。

A simple method to avoid interference of unwanted mode during tuning of a cavity resonator

When we tune a microwave cylindrical cavity resonator by varying its length with the help of a moving plunger, resonant frequencies of different modes may overlap to each other causing a noise problem. So, tunable range is influenced by the frequency overlapping of different modes. In this paper we describe a simple but effective method to increase the tunable range of a particular mode of a cylindrical cavity resonator. For this purpose we use a curved wall instead of a plane one as the moving wall to vary the length of the cylindrical cavity. Observations have been made with the help of HFSS.
