Query: Hyperbolic Metamaterial Feasible for Fabrication with Direct Laser
  Writing Processes   Stimulated emission depletion microscopy inspired direct laser writing
(STED-DLW) processes can offer diffraction-unlimited fabrication of
3D-structures, not possible with traditional electron-beam or optical
lithography. We propose a hyperbolic metamaterial for fabrication with
STED-DLW. First, we design meandering wire structures with three different
magnetic dipoles which can be excited under different incidences of light.
Then, based on effective parameters corresponding to normal incidence and
lateral incidence, we find that the hyperbolic dispersion relation for
five-layer structure appears between 15THz to 20THz. Finally, we investigate
the influence of imaginary parts of the effective parameters on the
metamaterial dispersion. The proposed metamaterial structure has also potential
for three-dimensionally isotropic permeability despite geometric anisotropy.
