Abstract :
Main characteristics of broadband helicon isolators for the metric and decametric wave ranges are discussed. With the use of equivalent circuits of the isolator, temperature dependencies of the backward attenuation and forward loss are analyzed. The agreement between the experiment and theory supports the validity of the circuit model.
