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…
