Embodiment Construction
[0033] In order to make the content of the present invention easier to understand, below in conjunction with accompanying drawing, the present invention is explained in further detail.
[0034] Figure 1-1 to Figure 1-2 The manufacturing process of the "one" type upper cover plate containing the positioning base of the terahertz metal rectangular waveguide is illustrated. Such as Picture 1-1 As shown, the upper and lower surfaces of a pure copper plate 1 with a length of L, a width of W, and a thickness of D are polished. Such as Figure 1-2 As shown, a gold layer 2 is electroplated on a randomly selected surface, and its thickness T 1 On the order of tens of nanometers to hundreds of nanometers, a "one" type upper cover plate 3 containing a positioning basal plane is obtained.
[0035] Figure 2-1 to Figure 2-8 The fabrication process of the waveguide body containing the "concave" waveguide cavity of the terahertz metal rectangular waveguide is illustrated. diagram 2-1...

The invention relates to a method for manufacturing a combined terahertz metal rectangular waveguide with its own positioning base, and belongs to the field of precision manufacturing of terahertz micro-devices. It is characterized in that: manufacturing the terahertz metal rectangular waveguide with a "one" type upper cover plate containing the positioning base; manufacturing the waveguide main body containing the "concave" waveguide cavity of the terahertz metal rectangular waveguide; A "one" type upper cover plate is combined with a waveguide body containing a "concave" waveguide cavity to manufacture a combined terahertz metal rectangular waveguide with its own positioning base. On the basis of realizing the precise and efficient manufacture of the combined terahertz metal-coated hollow rectangular waveguide, the present invention can solve the problem of difficult positioning when it is assembled with the flange, and is of great significance.
Description
technical field [0001] The invention relates to a method for manufacturing a combined terahertz metal rectangular waveguide with its own positioning base, and belongs to the field of precision manufacturing of terahertz micro-devices. Background technique [0002] Terahertz technology has become a research hotspot that has attracted much attention due to its huge application potential in national economic development and national strategic security. As early as 2004, the U.S. government rated it as one of the "Top Ten Technologies that Will Change the Future World", and the Japanese government even listed it as the first of the "Ten National Pillar Key Strategic Technologies" in 2005. The Chinese government held the "Xiangshan Science and Technology Conference" in 2005 and 2014 respectively, and formulated the blueprint for the development of my country's terahertz technology. A dozen or so tasks including new terahertz radiation sources for biomedical application research h...
