Embodiment Construction

[0024] The slotted waveguide to be prepared is as Figure 10 As shown, the following preparation process is adopted:

[0025] Step 1: Prepare the core mold. The core mold consists of two parts, the lower structure 4 and the upper structure 7. The lower structure 4 of the core mold is a rectangular nickel layer structure with a thickness of L2. The adjacent rectangular nickel layer structures have the same length. The upper layer of the core mold Structure 7 is a micro-cuboid column array structure with a thickness of L4, and the specific preparation method is as follows:

[0026] Step 1.1: coating a first layer of photoresist 2 with a thickness of L1 on the substrate 1;

[0027] Step 1.2: Place the substrate 1 after the first coating in step 1.1 on the stage of the photolithography machine, and use the first mask plate 3 to perform the first exposure;

[0028] Step 1.3: Put the substrate 1 after the first exposure in step 1.2 into the developing solution for the first develo...

Abstract

The invention provides a slot waveguide electric casting method and belongs to the field of electromachining. The slot waveguide electric casting method comprises the following steps of 1, preparing a core mold (8) composed of a lower-layer structure (4) and an upper-layer structure (7); 2, electrically casting copper onto the surface of the core mold (8) to obtain an electric casting body (9); 3, conducting precise polish-grinding on the surface of the electric casting body (9); and 4, cleaning the electric casting body (9), dissolving away the internal core mold (8) to obtain a slot waveguide. The slot waveguide electric casting method has the advantages that the machining precision is high, and the technological adaptability is high.

Description

Technical field [0001] The electroforming method of the slotted waveguide of the present invention mainly relates to electroforming processing and belongs to the technical field of electric processing. Background technique [0002] Terahertz waves refer to electromagnetic waves with frequencies ranging from 0.1 THz to 10 THz and wavelengths ranging from 0.03 mm to 3 mm. The unique properties of terahertz waves have had a profound impact on broadband communications, radar imaging, electronic countermeasures, electromagnetic weapons, security inspections, non-destructive testing and other fields, and have broad application prospects in the field of national security. For example, compared with microwave radar, terahertz radar has the advantages of high resolution, strong confidentiality, outstanding anti-interference ability, and strong ion body penetration ability. [0003] Metal waveguide is a commonly used transmission line in the THz low-frequency band. Among them, the me...
