【摘要】 波纹波导的特征方程是一个超越方程,求解的过程相当繁琐,Dragone提出了一种求解波纹圆波导特征方程的方法,本文首次推导了波纹圆波导中HE_mn、EH_mn和E₀₂模的渐近级数表达式,简化了波纹波导特征方程求解,有利于波纹圆锥喇叭的设计。更多还原

【Abstract】 The characteristic equalion of the corrugated wave-guide is a transcendental equation, and it is hard to solve. Dragone have put forward one new method to solve the characteristic equation of the corrugated wave-guide. In this paper we deduce the expression of the modes: HE_, EH_,and E₀₂ ; and get the asymptotic series solution. In this way , we can gel the solution more easier, furthermore it is useful for the design of corrugated horn in the antenna system.更多还原
