A novel three-dimensional FE procedure for the analysis of electron guns inside traveling wave tubes (TWTs) is presented, illustrating its main features. In this procedure, electron trajectories ...

A–D–A′–D–A-type nonfused-ring acceptors (NFRAs) have recently received extensive attention because of their suitable tuning of absorption spectra, frontier energy levels, and promising sunlight ...

Jahnavi Dangeti, a 23-year-old from Andhra Pradesh is going to space on an orbital flight with Titans Space as an Astronaut Candidate (ASCAN). Jahnavi is a graduate of Electronics and Communication ...

Results of numerical simulation of a miniaturized sub-THz traveling-wave tube amplifier with sheet electron beam and planar grating slow wave structure (SWS) are presented. Cold characteristics of the ...

Electron-phonon interactions — collisions between charge-carrying electrons and heat-carrying vibrations in the atomic lattice of the material — are considered the primary cause of electrons slowing ...

The 2D crystal lattice structure and bias-dependent contrast of a chiral electron donor−acceptor−donor triad system, composed of two oligo(p-phenylene vinylene) electron donors and a perylenediimide ...

China appears on the verge of carrying out a historic satellite-to-satellite refuelling mission in high orbit, a potential advance that has prompted the US to deploy two military surveillance ...
