Abstract: Powered by position-flexible antennas, the emerging fluid antenna system (FAS) technology is postulated as a key enabler for massive connectivity in 6G networks. The free movement of antenna ...
Abstract: We have numerically studied single-frequency gain-switched $\mathbf{2}-\boldsymbol{\mu} \mathbf{m}$ thulium doped fiber laser oscillator with cm-level long cavity length. The peak output ...
