Abstract: | Forced oscillations excited by a radial magnetic dipole in a dielectric hemisphere (resonator) placed on a perfectly conducting
plane are studied. It is shown that the dipole excites H modes. When the dipole radiation frequency equals the eigenfrequency of the resonator, an amplitude resonance is observed
in the spectrum. The excitation efficiency is high when the magnetic dipole is placed at the maximum of the radial field component
of the resonator’s eigenmode. |
