Abstract :
We have found by theoretical analysis that extraordinary EM wave transmission could occur for TE modes at frequency below the cutoff frequency of the hollow waveguide by inserting different kinds of anisotropic metamaterials (AMMs) in the hollow waveguide. Such transmission of EM energy has no lower cutoff frequency and is due to the conversion of the evanescent wave into propagating mode inside the AMMs, which is quite different from that in the case of waveguide loaded with an isotropic left-handed material slab. We believe that such AMM loaded waveguide structure could find applications in sub-wavelength microwave transmission or resonating components.
