Design of a miniaturized terahertz traveling wave tube with embedded single-walled carbon nanotubes cold cathode

Abstract In this paper, a miniaturized terahertz traveling wave tube (TWT) based on the embedded single-walled carbon nanotubes (SWCNTs) cold cathode electron source is studied. The cold cathode suitable for the terahertz TWT requires stable high emission current density and enhanced electron beam f...
