Abstract

A reconfigurable composite right/left-handed waveguide loaded by magnetic-metamaterial at a sub-wavelength scale is designed and investigated. The propagating mode in the reconfigurable magnetic-metamaterial waveguide (RMMW) can be switched between the left-handed and right-handed modes by changing the position of the metamaterial in the waveguide. Such RMMWs can be widely applied in the design of novel electronic devices. Numerical simulations are carried out to verify the controllability of the RMMW. Transmission characteristics, electromagnetic field distributions, dispersion curves, and effective constitutive parameters for the RMMW are simulated. It is shown that the simulation results are in good agreement with the theoretical predictions.
