The traveling-wave tube (TWT), also known as the traveling-wave amplifier (TWA) or
traveling-wave tube amplifier (TWTA), is a widely used amplifier in satellite communications …

Networks both within and outside the world of science are increasingly called upon to
handle very large amounts of data. It is said that we are entering the era of the industrial …

The Traveling Wave Tubes (TWT) is a powerful vacuum electronic device used to amplify
radio-frequency (RF) signals as well as numerous applications such as radar, television and …

To simulate traveling-wave tubes (TWTs) in time domain and, more generally, the wave-
particle interaction in vacuum devices, we developed the DIscrete MOdel with HAmiltonian …

The numerical simulations of the wave-particle interaction, as it occurs in particular in
traveling-wave tubes, require new tools especially to investigate near the band edges of …

A scheme to characterize and model the dynamics of the electron beam–electromagnetic
power exchange along a traveling-wave tube (TWT) is proposed. The method is based on …

Based on the double-periodic characteristics of a sine waveguide, the dispersion equation,
interaction impedance, and transmission losses of slow-wave structures are derived. The …

An analytical model of current propagation in a helical coil with varying geometry is
developed. It can be used for post-acceleration and post-focusing of ions produced via laser …

A phase shift that is caused by the machining errors of independent circuits would greatly
affect the efficiency of the power combination in traditional multi-beam structures. In this …
