Optimization of a Sheet Electron Beam Interaction with a Slow Wave
.
Pchelnikov Y., Yelizarov (Elizarov) A. A.
The model based on coupled impedance electrodes was used to analyze effectiveness of a sheet e-beam interaction with the in-phase mode of a slow wave. The coupling coefficient, characterizing the interaction effectiveness, was calculated using derivatives of the equivalent parameters, the specific capacitances and inductance. The calculated coefficient was compared with that of a cylindrical e-beam in a helix.

Decreasing energy consumption of devices is an important problem for modern Wi-Fi networks. To address this problem, the very first version of the Wi-Fi standard introduced a basic power saving mechanism. At the same time, the new IEEE 802.11ax and IEEE 802.11ba amendments describe modern power save mechanisms: target wake time (TWT) and wake-up radio ...
