analysis of axial-symmetric ring-shaped interface crack problems 軸對稱環(huán)形片狀界面裂紋問題分析
the axial-symmetric ring-shaped interface crack problems are discussed under tension loading 摘要討論受拉伸載荷作用的軸對稱環(huán)形片狀界面裂紋問題。
the procedure and methods for constructing new type microwave left-handed are summarized . by applying such approach, multiple new samples including the structures of symmetric rings, embedded rings, rings are desgined, realized and / or verified . 4 使用該種方法,設計、實現或驗證了包括對稱環(huán)、嵌套環(huán)、環(huán)等多種新型結構異向介質樣品,并對其性質進行了分析和仿真;4、首次實現了一種基于結構的一維各向異性異向介質樣品。
discussions and preliminary experiments are given for some potential applications of left-handed materials . experimental results which are in accordance with expects for the focusing of plane wave using symmetric rings and the focusing of radiate source using rings are obtained . simulation results are also obtained concerning the-like structure based backward radiate antenna and transmission line based left-handed structures 對稱環(huán)結構異向介質凹透鏡的平面波聚焦、結構異向介質的點源會聚等實驗都得到了和預期接近的初步結果;對基于結構全固態(tài)異向介質后向波介質天線微波異向介質的實驗研究和基于微帶電路結構單元的異向介質進行了計算機仿真研究,也取得了較好的結果。
