The dispersion characteristics of one-dimensional heterostructure with metamaterial is presented. We give a theoretical analysis and numerical simulations for tunable beam splitting and negative refraction. By adjusting the lattice constant of the heterostructure or the permeability of the metamaterial, the splitting angle can be tuned. Interestingly, if both the average permittivity and permeability...
We have numerically studied the characteristics of a slab waveguide loaded with dispersive anisotropic metamaterials. For two typical-structured metamaterials, we have analyzed the tensor expressions of frequency-dependent permittivity and permeability and discussed influences of the resonant cell structures on waveguiding characteristics. Numerical results show that the slab waveguide loaded with...
