Abstract :
A series of possible realisations of broadband helicon isolators for meter and decameter wave ranges has been analysed. The node model and scattering matrix of the isolators has been obtained. The characteristics of the designed devices have been investigated. On the basis of the Y-parameter matrix obtained for a nonreciprocal transformer, which contains a helicon resonator, the characteristics of some realisations of helicon isolators has been calculated. Comparison with experimental data ensures the adequacy of the model.
