WAVEGUIDE Y-CIRCULATOR WITH INSERT DISCS FROM MAGNETIC NANOPARTICLES BASED ON OPAL SUBMICRON SPHERES Russian patent published in 2024 - IPC H01P1/38 B82Y30/00 

FIELD: physics; electrical communication equipment.

SUBSTANCE: invention relates to microwave equipment and can be used as a decoupling device in radio equipment, i.e. is intended for directional transmission of high-frequency energy from a transmitting system to an antenna-waveguide system and directional transmission of reflected energy to a receiving system. In Y-circulator with magnetic material insert discs with T-shaped body with three rectangular waveguides arranged at angles of 120°, connected to transmission lines, two insert discs made of magnetic nanocomposites based on an opal matrix are arranged inside the housing in centre and are magnetized in a plane parallel to the axis of symmetry of the circulator and fitted on metal heat-absorbing platforms. Insert discs are made from magnetic nanocomposites based on opal matrix with periodic structure of submicron spheres SiO₂ with diameter from 200 to 280 nm, containing in interspherical spaces of opal matrix nanoparticles — Co₈₀Ni₂₀ with size of up to 50 nm.

EFFECT: wider range of operating frequencies, reduced direct losses, increased decoupling between channels, reduced reflection coefficient.
