Variational analysis of dispersion characteristics in disk - loaded waveguide slow - wave structures 盤荷波導(dǎo)慢波結(jié)構(gòu)色散特性的變分分析
Elliptical waveguides have found wide applications in a variety of microwave components : waveguide filters , radiators , resonators , and wide - band transmission lines , etc . periodic - loaded waveguides play very important roles in high - power microwave tubes , corrugated antennas and linear accelerators 在各種微波器件如濾波器、輻射器、諧振器和寬帶傳輸線中橢圓波導(dǎo)有著廣泛的應(yīng)用。周期加載波導(dǎo)在高功率微波管、波紋喇叭和線性加速器等中起著重要作用。
On the basis of complet ' : ly analyses about dual - m ( ) de phase shiftcrs , the finite - element formulation derives the variational principle for non - se1fadjoint electromagnetic problems which is microwave propagaticn in a aniso1ropic media loaded waveguide . then , the variatonal problem is approximated by a matrix eigenvalue problem 在此基礎(chǔ)上,詳細(xì)討論了利用有限元分析法這一強(qiáng)有力的工具來(lái)分析波導(dǎo)中填充各向異性介質(zhì)的問(wèn)題,導(dǎo)出了基于變分原理的泛函和有限元方程。
