摘要

本文设计了一种基于互补圆螺旋谐振结构的微波传感器，用于介质材料板的无损检测。该传感器是基于互补圆螺旋谐振器(CCSR)设计的，该谐振器在考虑的频段内有两个谐振频率。当传感器放置在待测材料(MUT)上时，可以观察到频率偏移和$S$11参数的变化。当样品中存在裂纹时也会发生这种情况。这种现象可用于介质板裂纹的无损检测。文中给出了数值结果，详细讨论了不同MUT和裂纹方向下共振频率和S$11参数的变化规律。

Microwave sensor based on complementary circular spiral resonator for non-destructive testing of cracks in dielectric plate

A microwave sensor inspired by the complementary circular spiral resonant structure is designed in this paper for the non-destructive testing of dielectric material plate. The sensor is designed based on the complementary circular spiral resonator (CCSR) which has two resonance frequencies in the considered frequency band. Frequency shift and variation of $S$11parameter is observed when the sensor is put over materials under testing (MUT). This also happens when the cracks exist in the sample. This phenomenon can be applied for the non-destructive testing of the cracks existing in the dielectric plates. Numerical results are given in the paper for a detailed discussion of the variation of the resonance frequencies and the $S$11parameter for different MUT and the orientations of the cracks.
