Problems solved by technology
However, when it is applied to the terahertz band, due to the limitation of the existing dielectric / metal waveguide using the process flow from the outside to the inside, it can only be plated to about 15 microns at most, and cannot be plated to the required mold thickness.
However, the drawn capillary can only be drawn to a minimum thickness of about 80 microns, so a dielectric layer with a thickness of 15-80 microns cannot be realized.

Abstract
The invention relates to a terahertz waveguide and a preparation method thereof. The preparation method comprises the following steps: drawing a prefabricated tube into a capillary tube by adopting a capillary tube wire drawing method; plating a metal film outside the capillary tube; plating a protective layer outside the metal film; and corroding the capillary tube by adopting a corrosion method. Different from a traditional method of plating a dielectric film in a metal film, the method comprises the following steps: firstly drawing the capillary tube which is made into the dielectric film, then plating the metal film, and finally corroding the capillary tube by a corrosion method, so that the thickness of the capillary tube can meet the optimal requirement.
Description
technical field [0001] The invention relates to the technical field of terahertz waveguides, in particular to a terahertz waveguide and a preparation method thereof. Background technique [0002] The metal / dielectric waveguide is obtained by plating a metal film and a dielectric film on the inner wall of the substrate tube respectively. Due to the existence of the dielectric film, the dielectric metal film waveguide increases the reflectivity of the inner surface of the waveguide, greatly increasing the proportion of energy in the air core during transmission, and dry air is a low absorption medium, so compared with the metal film waveguide, the metal The dielectric film waveguide reduces the transmission loss. [0003] Since the THz wave (terahertz wave) has multiple reflections at the interface of air / medium and the interface of medium / metal, the dielectric film in the dielectric metal film waveguide is like a Fabry-Perot interference cavity, combined with the hollow core...
