众所周知,毫米波技术在雷达、热核反应、导弹末制导、遥感和星际研究等领域有着广泛的应用,而毫米波传输线又是毫米波技术的一个重要方面。毫米波介质软波导就是适应这种发展而提出的一种新型传输线。在厘米波段,柔软波导通常是采用壁轧制成的波纹状矩形金属管,外部加橡胶层保护,但毫米波波段基模波导的尺寸越来越小时,采取这一工艺很困难,该结构的损耗也很大。新近发展的介质软波导
As we all know, millimeter-wave technology has a wide range of applications in radar, thermonuclear reaction, missile end-guidance, remote sensing and interstellar research fields, and millimeter wave transmission line is an important aspect of millimeter-wave technology. The millimeter-wave medium soft waveguide is a new type of transmission line proposed to adapt to this development. In the centimeter band, the flexible waveguide is usually made of corrugated rectangular metal tube wall rolling, the external plus rubber layer protection, but the millimeter wave band mode waveguide smaller and smaller, this process is difficult to take, the structure of Loss is also great. The newly developed medium soft waveguide
