“…We note that the polariton angle α is in the plane xy; the angle β, which is the angle between the incident wave and the principal axis x, is in the plane xz; the angle γ, which is the angle between the incident wave and the principal axis y, is in the plane yz. The transmission properties are tested by the THz time domain spectroscopy (THz-TDS) system [18][19][20][21].…”

We report the influence of two spatial incident angles on a terahertz polarizer, which is based on an aluminum slab with a center slit flanked by symmetrically distributed parallel grooves on both sides. Experimental results show that the polarizer shows narrow bandpass filtering effect with a very small divergence angle at normal incidence, which is very suitable for terahertz communication, and the extinction ratio (ER) can be achieved above 20 dB in the frequency band between 0.3 and 0.36 THz due to the excitation of spoof surface plasmon. As the structure rotates around the slit direction (β), the transmission peak will split into two and degrade quickly and the ER decreased down to 20 dB for β=10° at peak position. Rotating along grating period direction (γ) shows better tuning performance. The tuning frequency window can reach from 0.3 to 0.36 THz to promise an ER above 20 dB as γ is smaller than 25°.

“…With the corrugated disk, the six main dips are generated by coupling resonance between plasmonic waveguide and corrugated disk. Each of dip corresponds to a different mode [24], which is marked in Figure . Next, we analyze the resonance frequencies of these dips (1)(2)(3)(4)(5)(6). The phase change around the corrugated disk is calculated as [25]: (1) where is the propagation constant.…”

“…Terahertz functional components such as polarizers, modulators and filters, are crucial devices for different terahertz applications [1][2][3][4][5][6][7][8][9][10]. Metamaterial is one of particularly interesting components in terahertz region because these metallic microstructured objects derive most of their properties from their ability to support resonances.…”

We have experimentally excited terahertz multipolar Fano resonances in two asymmetrical metal particles: a defective corrugated metallic disk(CMD) structure and a hybrid structure consisted of a C-shaped resonator and a CMD. Furthermore, the Fano resonance modes can also be excited by the interaction between plasmonic waveguide and CMD. Our findings have shed light into the terahertz multipolar Fano resonances in asymmetrical CMD and opened the way to the design of terahertz plasmonic devices.

Modulation of terahertz properties of 3D ceramic photonic crystals via post‐creation non‐metal anion doping treatment

et al. 2019

Ceramic photonic crystals have wide application potentials for THz technology due to their characteristic strong chemical stability and high temperature resistance for demanding environment. However, it is still a challenge to modulate the THz properties of as-prepared ceramic TPCs via post-creation treatments to satisfy different application requirements. In this work, the THz properties of rutile TiO 2 ceramic 3D-TPCs were modulated by non-metal anion doping of either carbon or nitrogen, which was firstly created by the direct-writing technique with a TiO 2 sol-gel ink followed by the high temperature sintering process at 1200°C. Calcination of the pristine rutile TiO 2 ceramic 3D-TPCs in either CO or NH 3 atmosphere successfully doped either C or N dopants into rutile TiO 2 ceramic 3D-TPCs, respectively, which changed their dielectric properties and subsequently induced different THz properties on these ceramic 3D-TPCs with the same structure. Their THz properties were found to be largely affected by the specific nature of the dopant. Compared with the pristine rutile TiO 2 ceramic 3D-TPC, the bandgap positions of both C-doped and Ndoped rutile TiO 2 ceramic 3D-TPCs largely shifted toward the higher frequency, while the N-doped sample demonstrated a much broader bandgap. Thus, non-metal anion doping could be an effective post-creation approach to modulate the THz properties of ceramic TPCs.
