The super energy flows generated and transmitted have been investigated in a parallel-plate waveguide, which is filled with air and the anisotropic left-handed materials. Theoretical analysis and numerical simulations show that the propagation modes of the anisotropic super waveguide are consistent with those of the isotropic waveguides [1–3]. They also show that the loss of electromagnetic parameters size of waveguide will influence the amplitude of time-average power flows.
