本文推导了包含高阶模但忽略流场干扰效应的折叠四分之一波长边支谐振器的二端口矩阵。该模型被限制为同轴几何形状和两个折叠。推导是基于模式匹配技术，并通过原型上完成的测量进行验证。这些实验的一个值得注意的结果是靠近刚性壁的狭缝状泄漏的影响。最后，通过参数化的研究，探讨了不同长度和面积比的谐振器对谐振器性能的影响，得到了一套谐振器的设计规则。
This paper presents a derivation of the 2-port matrix for a folded quarter-wave side-branch resonator including higher order modes but neglecting flow interaction effects. The model is restricted to coaxial geometries and two-folds. The derivation is based on the mode matching technique and is verified by measurements done on prototypes. A notable result from these experiments is the effects of a slit-like leakage close to a rigid wall. A parametrical study finally investigates the influence of various lengths and area ratios of the resonator resulting in a set of design rules.
