Backscatter Cooperation in NOMA Communications Systems [PDF]
IEEE Transactions on Wireless Communications, 2021 In this paper, a backscatter cooperation (BC) scheme is proposed for non-orthogonal multiple access (NOMA) downlink transmission. The key idea is to enable one user to split and then backscatter part of its received signals to improve the reception at another user.

Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields
Angewandte Chemie, EarlyView.Four heavy Hg(II) coordination networks with paramagnetic Fe(II) sites reveal strong and halogen‐tunable low‐frequency (LF) sub‐terahertz phonons and field‐dependent magnetic transitions. LF phonon spectroscopy and Raman magnetospectroscopy are powerful probes of structure, low‐energy vibration, zero‐field splitting, and spin–phonon coupling supported ...
