DEMULTIPLEXER AT MAGNETOSTATIC WAVES Russian patent published in 2019 - IPC G02F1/00 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, particularly to microwave devices on magnetostatic waves, and can be used as a demultiplexer. Demultiplexer comprises substrate with first and second extended microwaves of iron-yttrium garnet arranged on it, input microstrip antenna, first and second output microstrip antennas, magnetic field sources connected to control means. Device also comprises third output microstrip antenna. First micro waveguide is placed directly on the substrate and is configured to excite the surface magnetostatic wave, and the input and first output antennas are placed on the opposite ends of the first microwave guide. Second micro waveguide is fixed above the first microwave guide perpendicular to the latter and is installed with overlapping of their central parts with a gap providing for possibility of pumping of surface magnetostatic wave from the first microwave guide to the second one. Second and third output antennas are arranged on opposite ends of the second microwave guide to receive reverse volume magnetostatic wave.

EFFECT: technical result consists in possibility to control frequency range and frequency band width of demultiplexer by means of static magnetic field effect.
