3D Analysis of Helical Slow-wave Structures for space TWTs:C [复制链接]

The  major  RF  performances  of  Traveling Wave Tubes (TWTs) are determined by the Slow-wave   Structure   (SWS),   which   is customarily  characterized  by   the    cold
parameters:   phase  velocity  (or   dispersion curve), interaction impedance and attenuation. The conventional procedures for evaluating these parameters make use of either analytical methods,   entailing   several   simplifying approximations,  or experimental approaches that produce results affected by measurement errors. While these methods have proven to be very successful in a number of instances, some
applications require high level of accuracy in particular for the phase velocity (typically in
the range of 0.5%.

谢谢,我现在在做慢波器件,可是有很多问题搞不懂,以前方向是半导体器件,想请教师兄可以从哪些方面入手? 多谢哦!
