Processing technology of terahertz frequency band feed source horn

The invention discloses a terahertz frequency band feed source horn processing technology, which comprises the following processing steps: S1, preparation work: splitting a whole workpiece into two parts, namely a corrugated groove tooth waveguide cavity and a square-circular conversion waveguide cavity, and then welding and forming the corrugated groove tooth waveguide cavity and the square-circular conversion waveguide cavity by using soft soldering; s2, cutting processing: converting the corrugated groove tooth waveguide cavity into a corrugated groove, and electroforming an aluminum core; and S3, electroforming: taking out the corrugated groove and the electroforming aluminum core, mounting screws at two ends, and fixing the corrugated groove and the electroforming aluminum core on an electroforming tool. The horn is processed and manufactured by adopting a processing method of electroforming and soft soldering, the basic principle of electroforming is that a required metal layer is obtained through an el
