FIELD: physics.SUBSTANCE: invention relates to microwave engineering, particularly to the millimeter wavelength range equipment, and can be used for absorbing Hwave of a circular waveguide. Core: the waveguide load consists of circular waveguide (1) with flange (2), dielectric hollow cone (3) and water jacket in form of cylinder (4) and cone (5) pipes. Dielectric hollow cone (3) is installed coaxially to round waveguide (1) with base towards flange (3). Cylindrical pipe (4) is arranged coaxially outside the circular waveguide (1) and is tightly closed at one end by flat cover (6), and at the other is by conical cover (7). Conical cover (7) is connected tightly with conical pipe (5) located outside equidistantly to hollow dielectric cone (3). In cylindrical pipe (4) there are perpendicular to the axis of circular waveguide (1) with gaps between themselves three flat annular diaphragms (8-10) with holes for water flow. Inlet water nozzle (11) is installed on cylindrical pipe (4) between flat cover (6) and first from it flat annular diaphragm (8). Outlet water nozzle (12) is arranged in conical tube (5) apex area. Dielectric hollow cone (3) is tightly attached to last flat circular membrane (10) with flange (13) made at the base. At that, cavity of holes for water flow in last flat annular membrane (10) are located outside area, which is in contact with dielectric hollow cone (3) flange (13).EFFECT: higher operational reliability.1 cl, 8 dwg |
