N槽结构波纹喇叭的理论分析
ANALYSIS OF N-SLOT STRUCTURE CORRUGATED HORN
-
摘要: 本文利用空间谐波法导出了N槽结构(每个周期有N个槽)波纹喇叭的特征方程和等效壁导纳的普遍公式,并把这些公式应用于双槽深波纹喇叭,给出了其等效壁导纳的表达式。文章还对一个双槽深波纹喇叭的等效壁导纳、特征值、口面模比和辐射方向图进行了数值计算,并与实验结果比较,两者吻合得很好。

Abstract: The general formulas of characteristic equation and equivalent wall admittance of corrugated horn having N-slot structure are derived by using the space-harmonic analysis method. As a special example, the expression for equivalent wall admittance of corrugated horn having dual depth combination is presented. The equivalent wall admittance, eigenvalues, mode coefficients on horn aperture and radiation patterns have been computed fora corrugated horn having dual depth combination. The calculated radiation patterns are in good agreement with the measured values. -
