MODELING OF A METASTRUCTURE BASED ON SPLIT-RING RESONATORS INCLUDING THE FERRITE ELEMENTS
A computer simulation of a metastructure based on four split-ring resonators with the inclusion of YIG (yttrium-iron garnet) ferrite elements on a GGG (gallium-gadolinium garnet) substrate was carried out in order to study the possibility of tuning the ferromagnetic resonance (FMR) line of 4 ferrite resonators under the influence of an external magnetic field. The design of a metastructure based on four split-ring resonators with YIG-GGG ferrite resonators and an equivalent resonator connection circuit are presented. This structure was considered earlier in terms of use for the development of a microstrip filter. The simulation was carried out using the Ansoft HFSS 3D modeling tool for RF/microwave fields. The obtained amplitude-frequency characteristics of the FMR show the possibility of resonance line tuning under the influence of an external magnetic field.
