Abstract:
This paper focuses on reduction of losses and dispersion effects on
tunnelling through waveguides filled with metamaterial. It will be shown that
these unwanted effects could be reduced by dividing the metamaterial into several
regions separated by air slabs. In the first part, these effects will be studied for
isotropic left-handed media (LHM). Later this will be substituted by an anisotropic
magnetic medium which will lead to a practical realization with broadside coupled
split ring resonators (BC-SRRs). Finally, it is shown that quasi-perfect tunnelling
is possible, even in the presence of unavoidable losses and dispersion in the
metamaterial.
