Abstract :
In this paper, the effects of placing a longitudinal slot in the channel region of a rectangular waveguide ENZ structure, are analyzed. A following investigation showed that changing the length of this slot can be employed to achieve tuning of only the tunneling frequency. Maximum resonant frequency shift reported is 11%. In addition, the equivalent circuit for the ENZ structure with this kind of slot configuration was derived with an excellent agreement between numerical and full-wave simulations.
