A discussion on molecular absorption noise in the terahertz band
Nano Communication Networks, 2016Abstract This paper focuses on molecular absorption noise caused by molecular absorption in the higher frequency bands, such as THz band (0.1–10 THz). This transmission induced noise has been predicted to exist in the THz band, since the conservation of energy requires the conservation of the absorbed energy in the medium. There exist multiple models

Practical dual-band terahertz imaging system
Applied Optics, 2017This paper introduces a dual-band terahertz imaging system as a potential product for nondestructive testing using heterodyne detectors and continuous-wave sources. The operating frequencies of the system are 110.4 and 220.8 GHz. Multiband fusion technology combines the advantages of the greater spatial resolution of the high-frequency band and the ...

Radio Simultaneous Localization and Mapping in the Terahertz Band.
2021In this paper, we introduce and experimentally validate a simultaneous localization and mapping (SLAM) algorithm based on the processing of radar data captured in the Terahertz (THz) band. We describe a measurement campaign carried out using a dedicated setup with the purpose to investigate the main properties of the signal backscattered in an indoor ...

An isotropy dual‐band terahertz metamaterial
Microwave and Optical Technology Letters, 2013AbstractAn isotropy terahertz (THz) metamaterial for dual‐band operation is designed and fabricated. The proposed metamaterial is composed of periodically arranged double metallic rings, and negative permittivity is obtained in 298–388 GHz and 652–780 GHz bands.

Measurements on penetration loss in terahertz band
2016 10th European Conference on Antennas and Propagation (EuCAP), 2016Results on penetration measurements through different materials at the terahertz band (0.1 – 10 THz) are reported. These materials include common materials found at any home or office, i.e., plastic, glass, paper, and hardboard. The measurements were conducted with terahertz time domain spectroscopy (THz-TDS) method and with the TeraView TeraPulse ...

Single and dual-band terahertz metamaterial
2013 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices, 2013Symmetric structures of single and dual-band metamaterial in the terahertz region are proposed, which composed of the electrical inductance-capacitance (ELC) resonate and electric field coupling resonate. Simulation results show that it can perform absorption peaks at one resonant frequency 0.716 THz with the absorption more than 95%, and at two ...
