Modelling of the Terahertz Communication Channel for In-vivo Nano-networks in the Presence of Noise [PDF]
, 2016 This paper focuses on the modelling of communication channel noise inside human tissues at the THz band (0.1-10THz). A novel model is put forward based on the study of the physical mechanism of the channel noise in the medium, which takes into account ...

Emission of terahertz radiation from SiC [PDF]
Applied Physics Letters, 2009 We report the emission of strong coherent broadband terahertz radiation from 6H-silicon-carbide (SiC) excited with optical pulses. The measured terahertz spectral signal-to-noise ratio is better than one thousand. We determine that the terahertz radiation is generated via second order optical nonlinearity (optical rectification).
