Non-reciprocal CRLH transmission line on substrate YIG

In this work, the modelling of composite right/left-handed transmission line and the CRLH transmission line theory have been studied. Then a parametric study of this components on YIG (with and without field) has been driven. Both experimental and simulated scattering parameters are shown, and the corresponding propagation constants are given, that enables to identify the different frequency bands: left-handed band, right-handed band and bandgap. This non-reciprocal metamaterials has potential to be used in radio frequency integrated circuits.
