In an earlier work [Cheng and Cui, Phys. Rev. B 72, 113112 (2005)], we have shown theoretically that extremely high power densities can be generated and transmitted in a super waveguide which is filled with homogeneous bilayers of right- and left-handed materials. In this paper, we realize such a super waveguide using right-handed transmission-line (RHTL) and left-handed transmission-line (LHTL) circuits. After a rigorous design of the RHTL-LHTL structure, we observe the generation and transmission of high-power densities in the super circuit waveguide from accurate simulation results. Both lossless and lossy cases have been studied for the LHTL circuit. From the simulation results and the rigorous analysis of energy speeds, we show that high-power flows with opposite directions are excited in the RHTL and LHTL parts of the super waveguide, which form the energy vortices in the waveguide cross section.
