本文主要是討論在空氣中一平面波正向入射至一披覆多層複合材料之多層旋光性介質平板之電磁反射與透射。我們以遞迴方式處理旋光性平板層與層之間的反射及透射係數,並利用波傳遞矩陣的方法處理複材的層與層之間的電磁場。由這個嚴謹的方法所計算得到的反射與透射矩陣結果,與狀態方程式的解析結果相當吻合。研究發現,若入射波為右旋圓極化波,則從多層旋光性平板反射與透射的分別只有左旋與右旋圓極化波,在旋光性平板披覆具非等向性特性的複合材料之後,則反射與透射的波兩者皆同時包含左旋與右旋圓極化波,這個特性在設計遮蔽或抗反射結構時提供更大的彈性。
This thesis presents an efficient eigenfunction-based model for analyzing the plane-wave reflection and transmission properties of a multilayered chiral slab with an embedded fiber-reinforced plastic composite (FRPC). In this model, the fields in each layer of the chiral slab are related recursively to those in the adjacent layer through eigenfunction-based reflection and transmission matrices, while the fields on the two surfaces of the FRPC are related to each other by an eigenfunction-composed wave transmission matrix modified from the one available in the literature. The proposed analysis model has been validated by comparing our computed results with data appearing in the literature. Many sample structures have been analyzed, assuring the flexibility and robustness of the model.
