Bessel Beam Optimization for Near-Field THz Communications under UE Location Uncertainty

Aditya Jolly, Vitaly Petrov, Gábor Fodor, Emil Björnson

To achieve the desired coverage and capacity levels, future terahertz (THz) wireless systems are envisioned to utilize extremely large antenna arrays. At THz frequencies, the combination of short wavelengths and large array apertures often makes many of the conventional far-field…

Unexpected Far-Near-Far Transition in Mobile Near Field Terahertz Communications

Peng Zhang, Hanmei Yuan, Zhe Wang, Vitaly Petrov, Emil Björnson

At THz frequencies, the radiative near-field distance can be sufficiently large to matter in real deployments. Existing near-field formulas are often understood in a simple way: as the link distance decreases, the propagation regime is expected to change only once, i.e., from far…
