Coupling Parameters Between a Dielectric Resonator and a Microstripline

The coupling coefficient between a microstripline and the dipolar magnetic (TE/0gamma delta/ ) mode of a cylindrical dielectric resonator is evaluated by using two methods numerical and analytical. Theoretical and experimental extenal quality factors, as well as the scattering matrix parameters which consider the substrate material, the ground plane, and the distance between the line and the resonator, are presented.

Ion-ion hybrid damping of magneto-acoustic resonances

The parametric dependence of the damping of fast magnetosonic resonances under ion-ion hybrid conditions is studied with respect to wave and mode number, frequency and species concentration. The experimental quality factors Q agree well with our theoretical model.
