Abstract

We present a bulk metamaterial with negative refractive index in the terahertz frequency range. The structure is composed of pairs of metallic crosses embedded in Benzocyclobutene (BCB). The design is specifically chosen to provide a low-loss, free-standing material which operates under normal incidence and independently of the polarization of the incident radiation. These qualities allow the fabrication of 3D structures by mechanical stacking of multiple thin films.

The cross pair structure. a) Schematic drawing of four unit cells with lattice constants ax =ay =90µm,az =62µm, length of a crossbar=81µm, width of a crossbar=21µm, separation of a cross pair=9.5µm. b) Microscope image of a single cross layer.

Amplitude transmittance of metamaterial slabs consisting of 1–4 layers of cross pairs. Comparison of the measured spectra (upper figure) with directly simulated curves (lower figure, solid lines) and curves derived from the transmission matrix of a one-layer structure under the assumption of independent layers (dashed lines).

Comparison of the amplitude transmittance between the cross pair and the single cross design for one layer of elementary cells.

Simulated phase of the electric field along a path through the metamaterial for a plane wave at 1.03 THz.

Fig. 6.

Effective material parameters retrieved from the simulated reflection and transmission data. (·)′ and (·)″ denote the real and imaginary part, respectively. The lefthanded transmission band is shaded. The dashed parts of the curves mark the regions where the half-wavelength inside the medium is smaller than the lattice constant az and the calculated effective parameters are not expected to be reliable.
