【摘要】 利用变容二极管制作了可调谐一维左右手组合材料.并对其进行了传输系数测量.实验发现当电压升高时,左手通带将向高频方向移动,而禁带的终止频率保持不变.基于微波传输线理论,给出了这种左右手组合材料的色散方程,实验曲线与理论曲线能够很好地符合.更多还原

【Abstract】 A new design of metamaterials of one dimensional periodic structure is presented in this paper and the transmission parameters are measured. The experiment results indicate that when the bias voltage rises the left-hand passband will move toward higher frequencies. Based on transmission line theory, the dispersive equation of the tunable metamaterials is given. The results of the theory agree very well with those of the experiments.更多还原
