【摘要】 对左手介质圆柱形波导的各种模式进行了理论分析,得到了特征方程。对几个低阶的圆对称模TEon模和TMon模进行了数值计算,绘制了归一化相位常数β=β/k0随归一化频率V的变化关系曲线,与普通介质圆柱形波导的相应模式进行了比较,指出了左手介质圆柱形波导中模式的一些反常特性。更多还原

【Abstract】 In this paper, Characteristics of left-handed material cylindrical waveguide modes are analysed. Dispersion equations are obtained. Numerical calculation of several low orders of cylindrical symmetrica TEon modes and TMon modes are investigated. Relationship curves of normalized phase constant β = β/k0 to normalized frequency V are drawed. To compare with general material waveguide modes, abnormal characteristics of the left-handed material cylindrical waveguide modes are obtained.更多还原
