摘要(中) 本論文建立了一套對於啞鈴型缺陷地面結構感測器新的分析與設計方法。在過去的文獻中僅提出在量測上低誤差之感測器但缺乏完整的設計方法。因此本研究利用統計方法歸納資料庫中導磁係數與介電系數量測低誤差的感測器。歸納分析結果發現除了感測器的等效電容和等效電感會造成導磁係數與介電系數的誤差外,不同待測物厚度也會影響量測結果。因此本研究先首自厚度0.4 mm之待測物資料庫中取出數組表現最佳的感測器,再從中找出誤差與厚度相關性較低的感測器。藉此取得量測更為精準之低誤差的感測器。
摘要(英) A new analysis and design method for dumbbell-shape DGS sensor is proposed in this thesis. The dumbbell-shape DGS sensor with low measurement error has been proposed in the past study. However, it is still required more complete design procedure. In this study, the sensors in database are generalized by statistical method based on low measurement error in permittivity and permeability. The result shows that not only the equivalent capacitance and
the equivalent inductance would cause error to these two values, the thickness about different DUT would also do. According to the result in the thesis, several sensors which perform better are selected from DUT database with 0.4 mm in thicknesses. Then among these sensors which have low relevance in thickness are selected which give better accuracy in measurement.
