Abstract
Introduction. The considered several works explore the question of electromagnetic resonance ferrite and dielectric resonators, the influence of electrodynamics system on the spectrum of magnetostatic oscillations ferrite resonator, the influence of metal wall on the spectrum of cylindrical dielectric resonator vibrations. Calculations of the electromagnetic field ferrite-dielectric resonator. The expressions for the components of the electromagnetic field outside the ferrite resonator for dielectric spectrum of fluctuations are obtained explicitly. The dependence of components of the external electromagnetic field on the coordinates r and θ for the main type of dielectric fluctuations spherical dielectric resonator H110 is calculated. The graphs of these dependencies are constructed. The comparison of expressions for the components of the electromagnetic field outside the ferrite resonator for dielectric spectrum fluctuations is conducted. These components are calculated using the technique of electromagnetic field excitation polarization currents with known expressions obtained by other methods. Conclusions. The investigation of the electromagnetic field ferrite resonator structure as a particular case of ferrite-dielectric resonator is conducted. The investigation of the external electromagnetic fields structure is carried out for the case of the main type of dielectric fluctuations using the method of calculating the excitation polarization currents of these fields. Polarization currents are found from the expression for the internal electromagnetic fields for basic type oscillation of ferrite resonator H110.
