WebApr 1, 2024 · Abstract—A compact planar meander-type slow-wave structure (SWS) for a W-band traveling-wave tube is studied. Computer simulation of the SWS electrodynamic parameters is performed. A new... WebAbstract: The dispersion characteristics of a planar tape-helix slow-wave structure (SWS) with straight-edge connections (PH-SEC) are evaluated by using effective dielectric constant (EDC) method. The EDC method helps to avoid the need to apply boundary conditions for straight-edge connections. The phase velocity obtained from the EDC-based analysis …

When normal individuals first fall asleep, they enter Stage 1 (sleep drowsiness) and then progress through Stages 2, 3, and 4 of NREM sleep. Stages 3 and 4 (deep sleep) are often called slow wave sleep or delta sleep because they are characterized by high amplitude, slow waves (also called delta waves) on EEG.
