Eutectic epsilon-near-zero metamaterial terahertz waveguides.
We present and analyze the unique phenomena of enhanced THz transmission through a subwavelength LiF dielectric rod lattice embedded in an epsilon-near-zero KCl host. Our experimental results in combination with theoretical calculations show that subwavelength waveguiding of terahertz radiation is achieved within an alkali-halide eutectic metamaterial as result of the coupling of Mie-resonance ...

متن کاملLattice models of nontrivial "optical spaces" based on metamaterial waveguides.
Metamaterials are being used to model various exotic "optical spaces" for such applications as novel lenses and cloaking. While most efforts are directed toward the engineering of continuously changing dielectric permittivity and magnetic permeability tensors, an alternative approach may be based on lattices of metamaterial waveguides. Here we demonstrate the power of the latter technique by pr...
متن کاملBulk plasmon-polaritons in hyperbolic nanorod metamaterial waveguides
Hyperbolic metamaterials comprised of an array of plasmonic nanorods provide a unique platform for designing optical sensors and integrating nonlinear and active nanophotonic functionalities. In this work, the waveguiding properties and mode structure of planar anisotropic metamaterial waveguides are characterized experimentally and theoretically. While ordinary modes are the typical guided mod...
متن کاملNanoscale metamaterial optical waveguides with ultrahigh refractive indices
We propose deep-subwavelength optical waveguides based on metal–dielectric multilayer indefinite metamaterials with ultrahigh effective refractive indices. Waveguide modes with different mode orders are systematically analyzed with numerical simulations based on both metal–dielectric multilayer structures and the effective medium approach. The dependences of waveguide mode indices, propagation ...
