This article presents a comparison between the specified dimensions given in document standards (IEEE Std 1785.2-2016) and the measured dimensions for interfaces used with rectangular metallic waveguides at submillimeter wavelengths. The standardized dimensions of these waveguide interfaces are compared with several waveguides in the WM-380 band (500–750 GHz) manufactured by two different companies. The measured electrical performance (in terms of reflection coefficient) for these waveguide interfaces is also compared with values given in documentary standards. The article shows that although the manufactured waveguides do not strictly adhere to the dimensions given in the standard, very good electrical performance is still achievable by using slightly different dimensions for the manufactured waveguide interfaces. The use of additional alignment dowel pins (as specified in the IEEE standard) further improves the electrical performance of these interfaces.

比较用于亚毫米波长的波导的标准化接口和制造商接口

本文介绍了文档标准 (IEEE Std 1785.2-2016) 中给出的指定尺寸与在亚毫米波长下与矩形金属波导一起使用的接口的测量尺寸之间的比较。将这些波导接口的标准化尺寸与两家不同公司制造的 WM-380 频段 (500–750 GHz) 的几种波导进行了比较。这些波导接口的测量电气性能（根据反射系数）也与文献标准中给出的值进行了比较。该文章表明，尽管制造的波导没有严格遵守标准中给出的尺寸，但通过对制造的波导界面使用略微不同的尺寸，仍然可以获得非常好的电气性能。
