LIQUID SHF MATCHED LOAD Russian patent published in 2018 - IPC H01P1/26 

FIELD: radio equipment and communications.

SUBSTANCE: invention relates to the field of radio equipment, in particular to the H₁₀ mode high-power electromagnetic wave energy absorption loads. Load contains the rectangular waveguide section, absorbing liquid in the metal vessel, separating the waveguide inner volume from the absorbing liquid radio transparent leak-tight partition. Radio transparent leak-tight partition consists of two docked plates, wherein the junction lies in the perpendicular to the wide wall waveguide plane of symmetry, and the plates are symmetrical with respect to the joint, at that, the angle (β) between the line formed by the waveguide wide wall and each of the plates intersection, and the waveguide wide wall axis of symmetry is equal to where a is the waveguide wide wall size, λ is the wavelength, and the angle (β) between the plate plane and the waveguide wide wall is equal to where ε – radio-absorbing dielectric relative dielectric permittivity modulus.

EFFECT: improvement in the matching and increase in the absorbed electromagnetic wave power.
