FIELD: manufacture of complex-shape waveguide sections for microwave, millimetric, and submillimetric wavebands. ^ SUBSTANCE: proposed method includes pressing of mandrel-mounted round billet by electromagnetic pulse applied in several cycles until desired shape of waveguide channel is attained, this procedure including vacuum annealing at t = 650 - 700 °C for minimum 30 minutes, etching of round billet during spaces between cycles, and fixation of flange on waveguide by using electromagnetic pulse applied upon shaping waveguide channel and flange seating. Depth of magnetic field penetration in metal is found from expression given in description of invention. ^ EFFECT: enlarged functional capabilities of method. ^ 1 cl, 5 dwg |
