Here we demonstrate the experimental results on in-house fabricated polymer THz porous fiber with sub-wavelength features. The experimental results confirm the theoretical prediction of low dispersion characteristics in a THz porous fiber as compared to a microwire.
This paper presents simulation and experimental results of a metallic wire-pair structure (H-pair) negative-index materials (NIM) and examine the dielectric characteristics of this structure in the THz frequency range using THz time-domain spectroscopy (TDS). This structure possesses negative index features at normal incidence. This makes measurements, that are otherwise difficult to carry out, possible...
In this work, fabrication and characterization of a negative-index metamaterial consisting of free-standing wire-pair composite structures is presented for application at THz frequencies. Complex index of refraction data is derived from amplitude- and phase-sensitive THz time-domain transmission and reflection measurements and compared with theoretical results. A first direct measurement of a negative...
