SPACE-FREQUENCY FILTER ON MAGNETOSTATIC WAVES Russian patent published in 2024 - IPC H01P1/218 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, in particular to microwave devices on magnetostatic waves, and can be used as a space-frequency filter on magnetostatic waves. Technical problem of the proposed invention is the creation of a filter on magnetostatic waves with the possibility of controlling the frequency range and forbidden zones. Technical result is achieved by the fact that a space-frequency filter on magnetostatic waves, comprising a substrate made from a film of gallium-gadolinium garnet, on which along the longitudinal axis there is a microwave guide from a film of iron-yttrium garnet, an input and output microstrip antennae located on opposite sides of the microwave guide, magnetic field source, according to the solution, the microwave guide has rectangular bases at the ends, changing into a zigzag section formed by segments of straight sections connected to each other by a turning angle, external magnetic field is oriented relative to the plane of the substrate along the Y axis.

EFFECT: possibility of smooth control of forbidden zones by changing magnetisation of the structure.
