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。
In this paper, the characteristic equation of the corrugated horn with N slots per cycle and the general formula of the equivalent wall admittance are deduced by the space harmonic method. The formulas are applied to the double-slot deep-corrugated horn. The equivalent wall admittance expression. The equivalent wall admittance, eigenvalue, die face ratio and radiation pattern of a double-groove deep corrugated horn are also numerically calculated and compared with the experimental results. The two agree well with each other.
