【正文】 摘要 I 摘要 隨著一系列通信的實(shí)際應(yīng)用需求的增長，毫米波真空器件得到了大范圍的應(yīng)用。而在各類毫米波真空器件中大多采用以波導(dǎo)為接口的輸出窗結(jié)構(gòu)。輸出窗的作用是隔絕真空器件內(nèi)部的真空和大氣的連接，但不妨礙微波功率的傳輸，這就要求輸出窗的設(shè)計(jì)必須滿足一定的能量傳輸要求。在窗內(nèi)要求有最小的反射或損耗，因此要求輸出窗匹配良好，工作頻帶寬，功率容量大，并且在一定頻寬內(nèi)其|S21|db。根 據(jù)這 要求設(shè)計(jì)滿足條件的輸出窗，不斷改變其參數(shù)設(shè)置，進(jìn)行多次仿真找到符合條件的輸出窗模型。微波仿真軟件 CST 為德國 CST 公司開發(fā)的高級無源濾波器件及天線仿真軟件包，能仿真多種微波真空器件，給出 S 等參量。本課程設(shè)計(jì)以 CST 軟件為基礎(chǔ)，設(shè)計(jì)理想模型并仿真，最后得出理想模型的尺寸與仿真參數(shù)。 關(guān)鍵字： 盒型窗 ,太赫茲輸出窗，非常規(guī)輸出窗 ,CST 軟件仿真Abstract II ABSTRACT As the growth of the practical application of a series of munications needs, millimeterwave vacuum device has been a wide range of applications. And mostly used in all kinds of millimeterwave vacuum device waveguide was favorable for the formation of the interface window of transmitting energy. Output window is used to isolate vacuum device inside the vacuum and atmospheric connection, but don39。t get in the way of microwave power transmission, which requires the output window design must satisfy certain energy transmission requirements. Requires minimal reflection or loss within the window, so the required output window matching is good, wide working frequency band, large capacity, power and the standing wave ratio within a certain bandwidth, |S21|db to these design satisfies the requirement of the output window, change the parameter Settings, multiple simulation find qualified model of the output microwave simulation software CST for Germany co mpany to develop advanced passive filter and antenna simulation software package that can simulate a variety of microwave vacuum devices, S and other parameters are course design based on the CST software, design the ideal model and simulation, and finally concludes that the size of the ideal model and simulation parameters. Key Words: Window box model design, Output Window Of THz, Irregular Type Window.
