MULTICHANNEL FILTER WITH SPATIAL SELECTION BASED ON A TWO-DIMENSIONAL MAGNON CRYSTAL Russian patent published in 2021 - IPC H01P1/215 H01P1/218 

FIELD: microwave radio engineering.

SUBSTANCE: invention relates to microwave radio engineering, in particular to devices on magnetostatic waves, and can be used as a power divider of a wave beam. The microwave signal filter contains a ferromagnetic film made of iron-yttrium garnet, which has the shape of a rectangle, the input and output converters of magnetostatic waves located on it, a number of holes are formed in the film, placed with the same period. The filter contains a second row of holes in the film, identical to the first and forming a two-dimensional magnon crystal with the first row, while the rows of holes are arranged symmetrically relative to the central axis of the rectangle along its edges, and the period of the holes is 350-400 mcm.

EFFECT: ability to control the operating mode when transmitting information by changing the amplitude and phase of the spin wave.
