WAVEGUIDE LOAD Russian patent published in 2004 - IPC

FIELD: microwave engineering; terminating loads of heavy-power plumbing.

SUBSTANCE: waveguide load has rectangular waveguide section and insulating insert passed through its inner space and filled with running absorbing fluid. Insulating insert it positioned orthogonally to longitudinal axis of waveguide in parallel with its wide wall. Stepped wedge-shaped piston is mounted past insulating insert, distance between insulating insert axis and mentioned piston being chosen so as to ensure that electromagnetic waves reflected from insulating insert and piston are out of phase.

EFFECT: improved matching, enhanced electric strength, reduced load size.
