Depth resolution enhancement of terahertz deconvolution by autoregressive spectral extrapolation

Dong, J. ; Locquet, A. ; Citrin, D. S.AbstractThis Letter presents a method for enhancing the depth resolution of terahertz deconvolution based on autoregressive (AR) spectral extrapolation. The terahertz frequency components with a high signal-to-noise ratio (SNR)...

Preparation, characterization, Raman, and terahertz spectroscopy study on carbon nanotubes, graphene nano-sheets, and onion like carbon materials

Abouelsayed, A. ; Anis, B. ; Hassaballa, S. ; Khalil, A. S. ; Rashed, U. M. ; Eid, K. A. ; Al-Ashkar, E.AbstractWe present the optical properties of carbon nanotubes, graphene nanosheets, and onion like carbon (OLC) samples with different cages size in wide frequency...

A terahertz in-line polarization converter based on through-via connected double layer slot structures

Woo, Jeong Min, Sajid Hussain, and Jae-Hyung Jang.AbstractA terahertz (THz) in-line polarization converter that yields a polarization conversion ratio as high as 99.9% is demonstrated at 1 THz. It has double-layer slot structures oriented in orthogonal directions that...

Manufacturing and terahertz wave modulation properties of graphene/Y3Fe5O12/Si hybrid nanostructures

Zhang, Dainan, Lichuan Jin, Tianlong Wen, Yulong Liao, Qiye Wen, Huaiwu Zhang, and Qinghui Yang.AbstractIn this paper, graphene/Bi:YIG(50 nm)/p-Si hybrid nanostructured graphene field effect transistors (GFETs) were fabricated at the first time. A 50 nm Bi-doped...
