Hybrid oscillations in composite resonators with uniaxial hexaferrites

The coupled oscillations are theoretically and experimentally investigated in the composite solid-state resonators (ferrite-dielectric structure). The experiments have been conducted for barium ferrite (BaFe
₁₂
O
₁₉
) and strontium hexagallate (SrGa
₁₂
O
₁₉
) plates in the saturation region. The calculation is carried out for the first four magnetostatic modes of ferrite plate. The obtained results do correlate with theoretical calculations.
