| Abstract: | This paper proposes a tunable zeroth-order resonator on a composite right/left-handed transmission line consisting of a transversely magnetized ferrite substrate periodically loaded by microstrip inductors.Based on the propagation theory of edge guided modes,the analysis procedure of this structure is introduced.The numerical results demonstrate the tunability of the resonant frequency by changing the DC bias magnetic field applied to the ferrite.In contrast to previous work,the proposed structure is easy to design and fabricate and does not require a chip component. |
