A submillimeter frequency multiplier. Part 2. Substantiation of a long-lived compact bunch model [PDF]

open access: yesРадиофизика и электроника, 2020
chanism of compact electron bunching has been revealed by numerical modeling and described. The pattern of long-lived compact electron bunches continuously moving along the surface of the clinotron comb-type slow-wave structure holds owing to the ...

Effects of magnetized plasma on the propagation properties of obliquely incident THz waves

open access: yesAIP Advances, 2017
In this paper, the propagation of obliquely incident terahertz (THz) wave in a non-uniform magnetized plasma slab is investigated. The electron density and the collision frequency across the plasma are assumed to have a Gaussian profile. To deal with the
