Large Signal Field Analysis of a Linear Beam Traveling Wave Amplifier for a Sheath-Helix Model of the Slow-Wave Structure Supported by Dielectric Rods. Part 2: Neumerical Results

Abstract

Numerical computation of induced surface current density, power gain, conversion efficiency, optimum interaction length and harmonic generation etc. pertaining to large-signal operation of a linear beam travelling wave tube amplifier (TWTA) employing a dielectric-loaded sheath helix model for the slow-wave structure based on the large-signal theory developed in Part 1 of this paper is presented, and comparison with the results of other large-signal theories and available experimental evidence is made.
