A Causal Channel Model for the Terahertz Band [PDF]
IEEE Transactions on Terahertz Science and Technology, 2018 Impulse response is vital for wireless communication analysis and modeling. This paper considers the impulse response of the terahertz band (THz band: 0.1–10 THz) for short range (1–100 cm) wireless communication. Earlier works derived the impulse response from transmittance by assuming a linear phase, which corresponds to a line-of-sight (LoS ...

Ultrafast carrier generation in Bi1-xSbx thin films induced by intense monocycle terahertz pulses [PDF]
EPJ Web of Conferences, 2019 Using terahertz-pump and terahertz-probe spectroscopy, we investigated terahertz-induced carrier generation processes in Bi1-xSbx thin films. The field dependence of the terahertz-induced transmittance change indicates distinct nonlinearity related to ...

Stochastic Geometry Analysis for Band-Limited Terahertz Band Communications [PDF]
2018 IEEE 87th Vehicular Technology Conference (VTC Spring), 2018 The terahertz band (0.1-10 THz) point-to-point links offer very large spectral resources for extremely high data rate links or an ability to share the resources among large numbers of users or devices. The latter case causes a need to consider interference in the THz band networks.

A multiband metamaterial absorber for GHz and THz simultaneously
Results in Physics, 2021 Nowadays, more and more metamaterial absorbers (MMAs) are explored not only in the microwave band but also in terahertz band, but few studies concentrate on metamaterial absorbers which can work in cross-band, that to say, absorb gigahertz (GHz) and ...

Channel modelling of human tissues at terahertz band [PDF]
2016 IEEE Wireless Communications and Networking Conference, 2016 In this paper, the channel model is proposed to compute the path loss, delay and noise at THz band of interest (0.5 THz ~ 1.5 THz). The results shows that THz band channel is strongly dependent on both the type of the medium and the distance while the concentration of water have a lot of influence because it not only causes attenuation to the THz wave ...
