摘　　要：基于热场动力学理论研究了热Fock态下量子效应对介观左手传输线微波段负折射系数的影响.结果表明:负折射系数随电流涨落的增加表现出线性递增的特点,而随温度的升高、频率的增大表现出锐减特性;负折射系数的变化幅度受光子数调控.该结论可对基于左手传输线开发的微波器件的微型化、集成化研究提供参考.The quantum effects on the negative refraction index of the mesoscopic left-handed transmission lines were investigated by the thermal field dynamics theory in microwave frequency band. The results indicate that the negative refraction index increases with the fluctuation of current and the decreases with the temperature and frequency emerge. And the negative refraction index rangeability is manipulated by the photon numbers. The conclusions can provide reference for the miniaturization and integration application of left-handed transmission.
