非理想金属表面高频电磁传输理论综述摘要摘要随着电子装备朝着高频带、高增益、快速响应、高密度和小型化方面的高速发展，机械结构因素对电性能的相互影响与相互制约越来越突出。诸多机械结构因素会对电子装备电性能指标产生影响，其中表面粗糙度因为其存在普遍、分布随机且其可复杂的影响电性能而备受瞩目。本文选取了电子装备中典型装备作为案例，研究对象为两大类，一是金属腔体结构，分为金属波导和腔体滤波器；二是金属面板结构，分为反射面天线和平板裂缝阵天线。针对装备的表面粗糙度对其电性能影响的研究与分析，研究内容主要是以下两大部分，一是当腔体结构内壁不是理想的光滑表面的时候，内部电磁场是如何传输的；二是当面板结构的表面不是理想的光滑表面是，其表面的电磁场是如何传输的。关键词：表面粗糙度波导腔体滤波器反射面天线平板裂缝阵天线ABSTRACTABSTRACTABSTRACTInrecentyears,alongwiththehightrendofelectronicequipmentstowardhigherfrequency,highergain,fasterresponse,higherdensityandsmallervolume,relationshipoftheactingonorinfluencingeachotherbetweentheelectronicperformanceandthemechanicalstructuralfactorsbecamemoreandmoreprotruding.Amongseveralmechanicalstructuralfactorswhichinfluencingtheelectronicperformanceoftheelectronicequipments,theroughnessattractedmuchaattentionofthescientistbecauseofitswidespreadpresence,randomdistributionandcomplicatedinfluences.Thispaperselectsthetypicalelectronicequipmentequipmentasthecase,thestudyincludetwocategories,oneisthemetalcavitystructure,includingmetalwaveguideandcavityfilter；anotheristhemetalpanelstructure,includingthereflectorantennaandplanarslottedwaveguidearrayanenna.Thisdissertationismainlyconcernedwitheffectofroughnessontheelectronicequipmentsintheprocessoftheresearchandanalysis,themainresearchcontentsarethefollowingtwoparts,oneiswhenthewallcavitystructureisnotidealsmoothsurface,themagneticfieldofinternalishowtotransmit;anotheriswhenthesurfaceofthepanelstructureisnotidealsmoothsurfaceis,theelectromagneticfieldofitssurfaceishowtotransmit.Keywords:SurfaceroughnessWaveguideFilterReflectorantennaPlanarslottedwaveguidearrayanennaPAGE\*MERGEFORMATii目录PAGE\*MERGEFORMATi目录TOC\o"1-3"\h\u目录HYPERLINK\l_Toc16165第一章绪论PAGEREF_Toc161651HYPERLINK\l_Toc133581.1研究背景PAGEREF_Toc133581HYPERLINK\l_Toc309461.2国内外研究现状PAGEREF_Toc309462HYPERLINK\l_Toc318861.2.1波导研究现状PAGEREF_Toc318862HYPERLINK\l_Toc11871.2.2滤波器研究现状PAGEREF_Toc11873HYPERLINK\l_Toc22
